摘要

微动目标对雷达回波产生调制

不同的信号形式调制效应也不同.正交频分复用(OFDM)雷达信号同时具有宽带距离分辨和窄带多普勒分辨能力

能更全面深入地揭示微动的调制效应.本文在建立微动散射点目标OFDM雷达回波模型的基础上

从高分辨距离像和微多普勒两个方面推导了微动对OFDM雷达回波的调制机理

并分析了调制效应与雷达参数、微动参数之间的关系

指出OFDM雷达信号结合了线性调频信号与脉冲多普勒雷达信号在微动分析方面的优势

为微动特征提取与目标识别提供了更有利的条件.仿真试验和暗室测量数据分析验证了结论的合理性.

Abstract

Targets with micro-motions have modulation effects on radar echoes

which vary for different radar waveforms.With high range resolution and Doppler resolution simultaneity

Orthogonal Frequency-Division Multiplexing (OFDM) radar signals can reveal the modulation effects more completely and more profoundly.At the beginning

based on the model of OFDM radar echoes of point-scattering targets with micro-motions

the modulation mechanism is derived

at two aspects of High Resolution Range Profile (HRRP) and micro-Doppler.And then

the relationship between the modulation effects

the parameters of radar and micro-motions is analyzed.It comes to a conclusion that the OFDM radar signals combine the advantage of Linear Frequency Modulated (LFM) signals and Pulse Doppler (PD) radar signals on micro-motion analysis

and they are more favorable for micro-motion feature extraction and target recognition.Finally

the results from simulations and anechoic chamber data prove the validity of the conclusion.
