NETWORKED RADAR OPTIMAL WAVEFORM DESIGN METHOD BASED ON LOW INTERCEPTION PERFORMANCE UNDER GAME CONDITIONS

摘要

Disclosed is a networked radar optimal waveform design method based on a low interception performance under game conditions. The method comprises: acquiring a frequency response, an ambient clutter power spectral density, an interference waveform, and an ambient noise power spectral density of each radar node in a target relative networked radar system; establishing a networked radar optimal waveform design model based on a low interception performance under game conditions, with an optimization objective of minimizing the total radiation energy of the networked radar system under the game conditions and with a constraint condition of meeting a preset target parameter estimation performance mutual information threshold, and performing adaptive optimization design on a transmitting waveform of each radar node; and iteratively solving the optimization model by using a necessary Karush-Kuhn-Tucker condition, so as to obtain each radar transmitting waveform under the conditions of meeting a preset target parameter estimation performance and using each radar transmitting waveform as an optimal solution. Therefore, the low interception performance of a networked radar system under a binary zero-sum game condition is effectively improved under the constraint of meeting a preset target parameter estimation performance.
