对间断窄带白噪声的功率谱进行了分析,得到其功率谱的表达式。对具有同步的间断噪声的射频脉冲序列的信噪比、具有连续噪声的射频脉冲序列的信噪比和具有连续噪声的射频余弦信号的信噪比进行了比较。证明脉冲多普勒雷达的速度检测灵敏度,可以达到相应的连续波雷达的速度检测灵敏度极限。
The power spectrum of intermittent narrow-band white noise is analyzed and the expression of its power spectrum is obtained. The signal-to-noise ratio of RF pulse sequences with synchronized intermittent noise, the signal-to-noise ratio of RF pulse sequences with continuous noise and the SNR of continuous-frequency radio-frequency cosine signals were compared. It is proved that the speed detection sensitivity of pulsed Doppler radar can reach the speed detection sensitivity limit of the corresponding CW radar.
