摘要：
The method of using a narrowband filter to realize matched filtering is derived. A novel method of using spectrum sampling to realize matched filtering is presented, and the method can conquer the disadvantages that the narrowband filter cannot adopt the adaptive scheduling of phased array radars and realize matched filtering for several waveforms. A novel error extraction method is proposed, which uses a time division multipath method to realize the intermediate frequency extraction. This method can save lots of space for vehicle-born radar systems, reduce the influence of amplitude and phase distortion caused by devices, and enhance the system reliability. Simulation results show that the spectrum sampling method is applicable, and the implementation of frequency spectrum sampling is elaborated.
