| () |
| Abstract: |
| This paper introduces the functions of a pulse compression signal generator,analyzes its advantages and disadvantages.It proposes to use direct intermediate frequency(IF) to realize pulse compression signal generator,and NLFM signal with bandwidth of 4 MHz can be generated.The harmonic suppression,noise in band and spurious suppression is no less than60dB,in complete consistence with the requirement of radar engineering project. |
| Key words: radar pulse compression signal generation IF generation IF sample NLFM |
