Method for restraining flight path deception jamming through remotely configured initiative and passive radar net

Abstract

The invention discloses a method for restraining flight path deception jamming through a remotely configured initiative and passive radar net. The method for restraining the flight path deception jamming through the remotely configured initiative and passive radar net mainly solves the problem that the prior art is large in calculated amount and large in data transmission amount. The method for restraining the flight path deception jamming through the remotely configured initiative and passive radar net comprises steps of 1, detecting a target through an initiative radar and a passive radar in the initiative and passive radar net and obtaining a measuring value of the target; 2, performing point trace correlated inspection on measuring values of the initiative radar and the passive radar, removing part of false targets of the initiative radar through a point trace correlated result Uij, tracking and filtering a reserved measuring value and obtaining target flight path information Bi'; 3, performing ambiguity processing on the point trace result Uij, tracking and filtering the measuring value of the passive radar through the processed result and obtaining the target flight path information; 4, performing flight path correlation detection on the target flight path information Bi' and the processed result and performing ambiguity processing on the target flight path information Bi' and the processed result; 5, identifying and removing false flight paths of the initiative radar through processed flight correlation result. The method for restraining the flight path deception jamming through the remotely configured initiative and passive radar net effectively restrains the flight path deception jamming and can be applied to the remotely configured initiative and passive radar net.

Description

technical field [0001] The present invention relates to the field of radar technology, in particular to track deception and interference countermeasure technology, and specifically to a method for suppressing track deception interference by using active and passive radar networks configured in different places. The method can be used in the data fusion center of the active and passive radar network, through Track correlation test, identify and eliminate false tracks formed by deceptive false targets, and improve the detection and tracking performance of active and passive radar networks under track deception interference. Background technique [0002] Deceptive interference refers to the indistinguishability between the interference signal and the target echo signal in the radar receiver, so that the radar cannot correctly detect the target information. The working principle of deceptive jamming is to transmit signals to the received radar, change its relevant parameters thr...

AI Technical Summary

Problems solved by technology

The point-track correlation method of active-passive radar network is to use the characteristics of active-passive radar network to realize the countermeasure against track deception interference, but this centralized fusion structure needs to use the method of correlation test to identify the active radar This process is quite cumbersome, and due to the adoption of a centralized fusion structure, the data transmission volume of the active and passive radar network is relatively large, and the survivability in the interference environment is reduced
