Abstract

The invention discloses a multi-target tracking transmission power allocation method for networked radars based on radio frequency stealth. The method comprises the following steps that S1, a predication Bayesian Cramer-Rao lower bound matrix for target state estimation errors with radar binary selection variables and radar transmission power as independent variables is constructed for a networkedradar system; S2, a multi-target tracking transmission power allocation model for the networked radars based on radio frequency stealth is established with predication tracking precision of a targetat the next moment and transmission resources of the networked radars as constraint conditions and the total transmission power of the minimized networked radar system as an optimization target; S3, the multi-target tracking transmission power allocation model for the networked radars is solved. The method improves the radio frequency stealth performance of the networked radar system during multi-target tracking.

Description

technical field [0001] The invention relates to radar signal processing, in particular to a radio frequency stealth-based networked radar multi-target tracking transmission power distribution method. Background technique [0002] Radar is widely regarded as the greatest invention for detecting objects at long distances since the invention of the telescope in 1608. This kind of electronic equipment known as "clairvoyance" and "wind ear" is more used in the military field, especially in the high-tech local wars since the 1990s, the role of radar has become more prominent. At the same time, radar-based electronic warfare systems have become an integral element of today's warfare. In electronic warfare, any party hopes that its own radar can effectively detect the opponent's target while avoiding detection and interception by the opponent as much as possible, so as to occupy the initiative on the battlefield and improve its own chance of survival. In this context, radar radio ...
