Waveform Design for Synthetic Impulse and Aperture Radar Based on LFM Signals

综合脉冲与孔径雷达(SIAR)是一种采用正交编码频率调制波形的多输入多输出(MIMO)雷达,本文对SIAR采用线性调频(LFM)脉冲信号时的波形设计问题进行研究.在对SIAR脉冲综合原理和LFM信号分析的基础上,给出了两种波形设计方法,对其性能进行了理论分析,并利用实际系统数据对其中一种波形进行了验证.计算机仿真结果和实测数据结果证实了这两种设计方法的有效性.

Synthetic impulse and aperture radar（SIAR） is a type of multiple-input multiple-output（MIMO） radar with frequency coded signals.This paper studies the problem of waveform design for SIAR based on linear frequency modulation（LFM） signals.On the basis of analysis on SIAR theory and LFM signals,two design methods are proposed and their performance is analyzed in theory.One method is verified through processing the real data.Computer simulation and real data processing results show that these methods are effective.
