Abstract: |
The signal modulation pattern identification and accurate parameter estimation algorithm for monopulse, LFM and phase coded radar signals are studied. Then, their hardware implementation platform is established with TMS320C6713. Testing results show that this method can deal with two simultaneously arriving signals. The processing time is 3748905ns and the error is less than 10 kHz . The processing speed and the precision can meet the requirement of practical system. |
