摘要

考虑到雷达成像信号处理方法对发射信号形式的需求,提出一种宽带MIMO雷达波形设计方法。首先,通过对发射方向图进行设计以实现对不同方向目标的同时观测。其次,在建立波形优化模型的过程中,将线性调频信号频谱作为期望发射频谱,并利用共轭梯度法对其进行求解,使得优化求解后得到的发射波形具有所期望的线性调频信号特性,解决了所设计发射信号为相位编码信号,对多普勒频移很敏感的问题。仿真实验验证了文中所提算法的有效性。

Abstract

Considering the demand of radar imaging signal processing method to the transmitting signal form, a MIMO radar waveform design method is proposed. Firstly, the transmitting beam pattern is designed to achieve the observation of the targets in different directions at the same time. Next, the spectrum of the LFM signal is used as desired transmitting spectrum while designing the waveform optimization model, the conjugate gradient is used to solve it and after the solution optimization the transmitting waveform with the characteristics of LFM signal is formed. This solved the problem that the phase coded signal is sensitive to Doppler frequency shift. In the end, the simulation has proved the effectiveness of the algorithm.
