Embodiment Construction

[0085] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0086] Take applying the method of the present invention to a shipboard platform as an example.

[0087] simulation one

[0088] Our fleet is in formation Figure 10 As shown, with ship A as the center of the circle, ships B to E are equally spaced on a circle with a radius of 13Km, and ships F and G are distributed on a circle with a radius of 45Km. Assume that the range of the ship-borne chaff bomb is 15Km, the search area radius of the anti-ship missile is 10Km, and the missile targets the center ship A, that is, the ship A is located on the missile bearing line. The outermost ships F and G are the centers respectively, and the area with the diameter of the missile search area as the radius is the threatened area of ​​the ship, and the cut-in attack ② area and the cut-in attack ④ area can be obtained; assuming that the missile is located i...

Abstract

The invention aims at solving the technical problems of how to realize cooperative jamming of anti-ship missile terminal guidance radar by using chaff projectiles among platforms in a multiplatform formation when the multiplatform formation is threaten by an anti-ship missile, as well as uncertainty of passive interference modes adopted to avoid an interference vacuum phase under the condition that starting time of the terminal guidance radar cannot be determined. When a certain platform is tracked by the terminal guidance radar, an interference area in which other platforms can be cooperated with the tracked platform is divided according to distribution conditions of the other platforms, and eventually, a specific cooperative jamming platform and an interference mode needing to be adopted are determined according to the area in which anti-ship missile is located. The method disclosed by the invention is particularly suitable for a ship-borne platform to use.

Description

technical field [0001] The invention belongs to the technical field of radar passive cooperative interference, and relates to a distributed passive cooperative interference method for anti-ship missile terminal guidance radar. Background technique [0002] Anti-ship missiles have always been the biggest threat to surface ships in modern naval warfare because of their long range, fast flight speed, high hit accuracy, good stealth effect, high power, and difficulty in interception. In the jamming of anti-ship missile terminal guidance radar, chaff passive jamming, which is widely used at present, is still one of the most effective anti-missile means, because the chaff jamming cloud formed by chaff bombs not only has a large reflection area, Interference frequency bandwidth and other characteristics, and its drift speed in the air is similar to the speed of ship movement, so it is not easy to be distinguished and identified by anti-ship missiles. Therefore, it is still of grea...
