一种认知 MTD 雷达脉间编码设计方法
A Design Method for Inter-Pulse Coding for Cognitive Moving Target Detecting Radar
摘要
Abstract
Cognitive moving target detection(MTD)radar system changes its transmission according to time-varying clutter environment,so as to improve the signal-clutter-and-noise ratio (SCNR).Aiming at the problem of MTD radar transmit code design in the presence of signal-dependent clutter,we study MTD radar model based on pulse coding in slow-time domain and discuss the feasibility of SCNR improvement.The in-ter-pulse code optimization design criteria for improving SCNR is proposed and a simplified method of optimi-zation problems is presented.Considering the cone constrained quadratic programming(CCQP)problem,an algorithm for optimizing the code based on reduced gradient is given.The simulation results show that slow-time domain coding can effectively improve SCNR and the algorithm has the characteristics of small computa-tional complexity and good real-time performance.关键词
