This paper first presents the fundamentals of DDS, and then gives a method of accomplishing digital synthesis of FM signals by means of dual DDS structures.
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。
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.
