| Abstract: | The spectrum characteristics of synchronous jamming on range and velocity are analyzed. A method for a PD radar to counter the jamming is also discussed. Based on the measurement of the AGC voltage and the analysis of the spectrum of input signals, judgement and countermeasure against synchronous jamming on range and velocity are realized in a range-velocity tracking system constructed by high speed, programmable DSP chips. |
