The simulation result shows that VPSD is a kind of constant false alarm rate detector, which can detect HFM signal effectively in low SNR, and can adapt to the Doppler mismatch very well.
仿真结果表明，周期斜率方差检测器是一种恒虚警概率检测器，在较低信噪比下可有效检测双曲调频信号，并对多普勒失配有很好的适配性。
Airborne pulse doppler weather radar could display clear colorized weather image dynamically on its screen and give pilots alarm about the extreme weather area to avoid risk betimes.
机载脉冲多普勒气象雷达则能够用清晰的图像实时显示出飞机前方的气象状况，并及时将极端天气的报警信息提供给飞行员，以提前躲避危险。
It uses a conventional constant false-alarm-rate(CFAR) detection procedure but the thresholding scheme is based on regression analysis of power spectrum values along range and Doppler cells.
该方法采用传统的恒虚警率（CFAR）检测方法，但其门限设置是基于沿距离和多普勒单元功率谱值的回归分析。
