【Abstract】 Because of the low precision,low capability of detection and lack of flexibility of traditional analog radar altimeter signal processing,a design of all-digital radar altimeter signal processor based on FFT and constant beat-frequency modulation is proposed to assure the design with higher precision,higher stability,and higher flexibility.The probability and validity of this design are verified by simulation.更多还原
