| 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. |
