Abstract :
A kind of signal processing method combing autocorrelation detection and FM harmonic detection technology is presented for the radio ranging system based on pseudo-random binary-phase code and linear frequency combined modulation. The mathematic model of ranging system is studied. The virtual simulation model for ranging system is established and the ranging property is analyzed. The simulation results of ranging resolution are consonant with the calculation values. The results are addressed that the ranging method has excellent ranging precision.
