Optimal Multi-function Waveform Design for MIMO Radar with Collocated Antennas

摘要

摘要: 针对集中式多输入多输出(MIMO)雷达波形设计中多个设计目标同时优化的问题，基于交替投影的思想，该文提出一种以任意维迭代谱逼近算法(ADISAA)为基础的波形设计框架，通过可调的权重来协调发射方向图匹配、良好的相关特性和频谱凹口等多种功能的波形设计目标，最终实现恒模波形设计。仿真结果表明，相对于已有的算法，在发射方向图匹配的基础上，该算法改善了发射波形在指定区间的相关特性，同时通过频谱凹口的设计避开了受到色噪声和有源干扰污染的频段，算法的计算复杂度更低。

Abstract: This paper addresses the simultaneous optimization problem of the multi-objective waveform design for MIMO radar with collocated antennas. Inspired from the idea of alternating projection, a waveform design framework is presented based on the Arbitrary-Dimensional Iterative Spectral Approximation Algorithm (ADISAA). Multi-objective of waveform design such as transmit beampattern match, good correlation, spectrum notch can be controlled by the adjustable weights. Finally, the constant modulus signal is designed. Simulation results show: the proposed algorithm improves the correlation performance of waveform at a specified lag intervals after transmit beampattern matching, the spectrum notch is designed to avoid the spectrum band which is polluted by active jamming and color noise, and it has lower computational complexity.
