RU2500970C1 - Method of setting values of interference emission (jamming) parameters - Google Patents

Abstract

FIELD: radio engineering, communication.

SUBSTANCE: method of setting values of parameters of emitting (shooting) expendable electronic warfare means involves emitting (shooting) expendable electronic warfare means in form of separate loads from a facility according to a program which includes parameters with independently set values based on which the number of released loads and the rate of release are set. The time of beginning execution of the program, the number and type of released loads for each release and the rate of release are specified in the program. Time intervals between groups and within groups may assume an arbitrary, optionally identical value. Combination of different types of loads in different amounts with simultaneous release (shoot) is possible. In the program, repeating releases are merged into groups, which in turn may be merged into higher-level groups and the program can be executed to protect different facilities (mobile, fixed, ground-based, underwater, air).

EFFECT: high efficiency of using expendable means and facility protection as a whole.

Description

The method relates to electronic warfare and can be used to protect objects (both mobile and stationary) from being hit by enemy guided missiles with homing heads. Consumable electronic warfare means in the form of individual cargoes are thrown out (shot) simultaneously and sequentially, in the order specified by the “shooting program”, containing parameter values (quantity, type of dumped cargo, dumping rate), while the parameter values are independently settable values. The method allows to improve the protection of objects from guided missiles.

A known method of protecting an aircraft using consumable electronic warfare means according to a program containing parameters with independently set values that specify the number of discharged loads and the discharge rate (RF patent No. 2229667, IPC F41F 3/04, B64D 1/08, B64D 1 / 02, B64D 1/14).

The disadvantage of this method is the lack of effectiveness of the application, since the method does not take into account the possibility of using various objects (for example, vehicles moving on the surface of water and land, land storage, etc.) that are destroyed by guided missiles, and does not allow wide sense of the word vary the values of the parameters of the shooting program.

The present method is aimed at solving the problem of increasing the efficiency of the known method by introducing additional parameters of the shooting program and the possibility of their mutually independent task. The problem is solved as follows.

In the known method, consumable electronic warfare means in the form of individual cargoes are thrown out (shot) from the aircraft sequentially, according to a program containing parameters with independently set values, by which the number of cargoes dropped and the discharge rate containing equal predetermined intervals between the same categories (called volleys) are set , series, sequences).

Compared with the known, the claimed method:

- uses new parameters of the shooting program;

- determines the order of setting parameters for the implementation of the ejection (shooting);

- allows you to change both the number of shot goods and their type;

- allows you to combine different types of cargo while shooting;

- allows you to vary the time intervals between equivalent categories;

- expands the scope of this method for various objects (it is possible to use in the protection of aircraft, mobile and stationary ground and surface objects).

When using the method, the efficiency of the use of expendable funds in real applications is increased, taking into account the situation and the nature of the emerging threats.

To implement the proposed method, the shooting program is described by the following parameters:

Parameter T ₀ (the initial time of shooting, the specified time delay of shooting) - sets the time interval between receipt of the shooting program and the start of shooting, determines the time t ₀ at which shooting will begin.

Parameter K _ij sets the amount of cargo of type i discharged in the jth outlier. Respectively:

i - type of cargo, can take values from 1 to m,

m is the number of types of cargo,

j is the number of the outlier, can take values from 1 to n,

n is the number of emissions.

An ejection (ejection, shot, flash, shooting, volley), in which at the same time (simultaneously) ejected (shoot) loads of various specified types in a certain specified quantity, is described by the parameter Z _j :

Zj = {K _1j , K _2j , ..., K _mj },

where the parameter T _j determines the time interval between discharges (shots, flashes, shootings, volleys).

If it is necessary to repeat the outbursts (discharges, shots, flashes, shootings, volleys), it is possible to combine them into a group (series, frame).

In this case, the group (series, frame) is described by the parameter S _q :

S _q = (Z ₁ , T ₁ , Z ₂ , T ₂ , ..., T _n-1 , Z _n ),

where q is the group number, can take a value from 1 to p,

p is the number of repeated groups.

The time interval between groups is determined by the parameter D _q .

производится аналогично вышеизложенному. Временная диаграмма программы отстрела, заданной описанными параметрами, приведена на фигуре 1.In accordance with the task and implementation conditions, it is possible to further combine repeating groups into groups of a higher level (sequences, episodes). The characteristics of groups (sequences, episodes) of level x will be determined by the parameter $$S_q^x$$

produced similarly to the foregoing. The timing diagram of the shooting program specified by the described parameters is shown in figure 1.

The task and transmission of the values of the parameters of the shooting program is performed by an array of data. General view of the array is presented in figure 2.

The essence of the method is illustrated by examples.

Example 1

Conditions: One cargo is available.

Requirement: It is necessary to make its single shooting without delay.

) могут не задаваться и при формировании массива не учитываются, либо быть приравнены к нулю.Implementation: We determine the values of the parameters of the shooting programs according to the conditions and requirements. We get: y _max = 0, K ₁₁ = 1, T ₀ = 0. The remaining parameters (K ₂₁ ... K _mn , T _j , p ... p ^x , $$D_{\mathrm{one}}...D_{y-\mathrm{one}}^x$$

) may not be specified and are not taken into account when forming the array, or be equal to zero.

Example 2

Conditions: One type of cargo is available.

Requirement: It is necessary to shoot cargo one at a time without delay in accordance with the set discharge rate:

Volley - 3;

Volley interval - 20 ms;

Series - 2;

Series Interval - 2 s;

The sequence is 3;

The sequence interval is 6 s.

Implementation: We determine the values of the parameters of the shooting programs according to the conditions and requirements.

We get:

y _max = 2;

T ₀ = 0;

m is 1;

n is 3;

K ₁₁ = K ₁₂ = K ₁₃ = 1;

T ₁ = T ₂ = 20 ms;

p is 2;

D ₁ = D ₂ = 2 s;

p ² = 3;

$$D_{\mathrm{one}}^2=D_2^2=6c$$

The remaining parameters may not be set and, when forming the array, not be taken into account or be equal to zero.

Example 3

Conditions: There are two types of cargo.

Requirement: It is necessary to shoot cargo in accordance with the specified parameters:

Delay 1.5 s. Reset 1 - drop 1 load of type 1, 2 loads of 2 types. Maintain an interval of 10 ms. Dump 2 - dump 3 loads of 2 types. Maintain an interval of 2 s. Repeat Reset 1. Hold for 10 ms. Repeat reset 2. Hold for 1.5 s. Repeat Reset 1. Hold for 10 ms. Repeat reset 2.

Implementation: We determine the values of the parameters of the shooting programs according to the conditions and requirements.

We get:

y _max = 1;

T ₀ = 1.5 s;

m is 2;

n is 2;

K ₁₁ = 1;

K ₂₁ = 2;

K ₁₂ = 0

K ₂₂ = 3;

T ₁ = 10 ms;

p is 3;

D ₁ = 2 s;

D ₂ = 1.5 s.

The remaining parameters may not be set and, when forming the array, not be taken into account or be equal to zero.

Thus, the application of the described method in comparison with the prototype allows you to take into account the features of the characteristics and actions of the object and the threat, the conditions of implementation and their predicted change, to form an ejection program with variable characteristics and thereby increase the efficiency of the use of expendable funds and protection of the object as a whole.
