MIMO雷达发射方向图匹配和波形优化方法

Abstract

Abstract:

A covariance matrix of transmit signal waveforms is optimized via semi-definite programming (SDP) for matching the desired transmit beampattern of an MIMO radar system. Based on the covariance matrix above and using the cyclic algorithm (CA) and the min-max method proposed, low space-time sidelobes are achieved by optimizing waveform phases of the transmit signal waveforms with constant modulus. Additionally, a convex programming method is proposed to design the space-time mismatched filters, and then the space-time sidelobes are furthermore reduced.

Key words: MIMO radar, transmit beampattern matching design, waveform optimization, min-max method, convex programming
