| 摘 要： | 线性调频连续波（ＬＦＭＣＷ）雷达在理论上具有很高的测距精度和距离分辨力,但实际的ＬＦＭＣＷ雷达由于其固有的扫频非线性而使其实际的测距精度和距离分辨力下降,本文根据ＬＦＭＣＷ雷达回波功率谱的特性,从理论上分析了扫频非线性对ＬＦＭＣＷ雷达测距精度和距离分辨力的影响,为实际ＬＦＭＣＷ雷达扫频非线性的外部校正提供一个精确的理论依据。

| Abstract: | Linear frequency modulation continuous wave (LFMCW) radar has high theoretical range precision and range resolution,but its practical range precision and range resolution will decrease because of its inherent nonlinearity in frequency sweep.This paper analyses theoretically the effects of the nonlinearity on the range precision and range resolution of LFMCW radar according to its echo power spectrum,and gives accurately theoretical grounds for outside correction of the nonlinearity of LFMCW radar. |
