Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings.

[0050] Starting from practical engineering applications, the present invention proposes a radar transmission parameter optimization method for radio frequency stealth and target tracking, which reduces the interception probability of the enemy's passive detection system for the multi-base radar transmission signal, and improves the multi-base radar target tracking accuracy. Therefore, the radio frequency stealth performance and target tracking performance of the multi-base radar system are effectively improved.

[0051] The multi-base radar transmission parameter optimization method oriented to radio frequency stealth and target tracking of the present invention, firstly, considering the scene of multi-base radar target tracking, the interactive multi-model extended Kalman filter algorithm is used to track the target, and the passive detection system is used to detect t...

Abstract

The invention discloses a multi-base radar transmitting parameter optimization method for radio frequency stealth and target tracking. The method comprises the following steps of: S1, determining a multi-base radar target tracking scene; S2, determining a performance index representing multi-base radar radio frequency stealth; S3, determining a performance index representing multi-base radar target tracking; S4, establishing a multi-base radar transmitting parameter optimization mathematical model for radio frequency stealth and target tracking; and S5, solving the multi-base radar transmitting parameter optimization mathematical model for radio frequency stealth and target tracking. According to the method, the radio frequency stealth performance and the target tracking performance of themulti-base radar in the tracking process are optimized at the same time, the interception probability of an enemy passive detection system on multi-base radar transmitting signals is reduced, the radio frequency stealth performance of the multi-base radar is improved, and the target tracking precision is improved.

Description

technical field [0001] The invention relates to radar signal processing technology, in particular to a multi-base radar transmission parameter optimization method for radio frequency stealth and target tracking. Background technique [0002] The modern radar battlefield environment is becoming more and more complex. As an important active stealth technology, radar radio frequency stealth technology is the key to resisting the enemy's passive detection system and ensuring that the radar detection system and its carrying platform discover, strike and destroy the enemy first. important technical means. [0003] Adaptive adjustment of radar transmission parameters realizes the closed-loop processing from the radar receiver to the transmitter. Through the continuous change of the target during the tracking process, the radar transmission parameters are optimized to maximize the effectiveness of various resources in an increasingly complex environment. Therefore, the optimal desi...
