| 摘 要： | 在白噪声与线性调频连续波重达回波功率语的关系基础上，从理论上分析了白噪声对线性调频连续波重达到距精度和距离分辨力的影响。分析结果表明，雷达采用“差拍－傅里叶”结构在频域上获取目标信息要比采用“差拍－平均频率计数”结构在时域上获取目标信息具有更强的抗噪声性能。

| Abstract: | This paper theoretically analyzes the relationship between white noise and power spectrum of linearfrequency modulation continuous wave (LFMCM) radar and the influence of white noise on its range-precision andrange-resolution. The result is derived that LFMCW radar has higher anti-noise property which adopts the structure ofBeat-FFT than that of Average Frequency Counter |
