| Abstract: |
| A new ranging method based on quadric difference frequency is presented. The principle of ranging is deduced in details. The rules for frequency selection are proposed，which make convenient the design of transmitter and later signal processing. The need for SNR is analyzed when solving ambiguity correctly. Compared with the uneven ranging method, its advantages are proved. Simulation results verify the validity of the method. |
