Embodiment Construction

[0075] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0076] like figure 1 As shown, the radio frequency stealth-based multi-base radar radiation parameter multi-objective joint optimization method of the present invention comprises the following steps:

[0077] 1. Determine the composition and working parameters of the multistatic radar system:

[0078] Considered by M R A multi-base radar system composed of two-coordinate phased array radars that are distributed in space and maintain space, time, and frequency synchronization. Each radar can only receive and process target echo signals from its own transmitted waveforms. At the same time, each time External radars can only track at most one target. In addition, set the multi-base radar operating parameters, target tracking accuracy threshold, the upper and lower limits of the residence time of each radar illuminated...

Abstract

The invention discloses a multi-target joint optimization method for multi-base radar radiation parameters based on radio frequency stealth. The method comprises the steps of determining the components and working parameters of a multi-base radar system; constructing a prediction Bayesian Cramer-Rao lower bound matrix taking a radar binary selection variable, a radar sampling interval, the residence time and the transmitted signal bandwidth as independent variables, and taking the prediction Bayesian Cramer-Rao lower bound matrix as a measurement index of the prediction tracking precision ofa moving target at the next moment; establishing a multi-target joint optimization model for the multi-base radar radiation parameters based on radio frequency stealth; and solving the joint optimization model. According to the method, under the condition that the emission resource constraint of the multi-base radar system at the next moment is satisfied, parameters such as the radar distributionmode, the sampling interval of the radiation radar, the residence time and the transmitted signal bandwidth are subjected to joint optimization design by taking the minimization of the total residencetime of the multi-base radar to all targets and the sum of the prediction tracking precision of all irradiation targets at the next moment as an optimization target, and the radio frequency stealth performance of the multi-base radar system during multi-target tracking is further improved.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a radio frequency stealth-based multi-objective joint optimization method for radiation parameters of multi-base radars. Background technique [0002] The experience and lessons of the Gulf War tell us that seizing electromagnetic dominance on the battlefield and gaining air dominance play a decisive role in the victory of the war. In order to be able to detect and attack the enemy first in the war, it is necessary to vigorously develop radar radio frequency stealth technology. Radar radio frequency stealth technology refers to the target characteristic reduction control technology of radar radio frequency radiation signal, the purpose is to increase the difficulty of signal detection, sorting and identification of enemy radio frequency passive detection system, and realize the radar system relative to the enemy radio frequency passive detection system...
