PULSE MODULATION SIGNAL SPECIFICATION METHOD, PULSE MODULATION SIGNAL DISCRIMINATION METHOD, AND PULSE MODULATION SIGNAL DISCRIMINATION DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a new pulse modulation signal specification method, a pulse modulation signal discrimination method, and a pulse modulation signal discrimination device, capable of detecting a characteristic of a video pulse signal, and performing discrimination processing of a pulse modulation signal by using the characteristic at high speed with high performance, without performing a great deal of calculation processing such as multi-bit high-rate A/D conversion and FFT (Fast Fourier Transform) which has been performed for pulse modulation signal specification or pulse modulation signal discrimination in a radar signal discrimination device. PSOLUTION: In this pulse modulation signal specification method, a video pulse signal acquired by performing envelope detection of an incoming radio wave constituted of a pulse modulation signal is separated into each prescribed band, and a zero crossing point of the separated video pulse signal is detected within a prescribed range in each prescribed band, and the zero crossing point in each prescribed band is used as a characteristic of the video pulse signal, to thereby specify a pulse train of the incoming radio wave.
