| Abstract: | According to the theory of radar signal analysis, a method is put forward which separates the radar echo wave signal turned from the target from the mixture of radar echo wave with jamming signal at the video terminal of radar, and a method is also put forward by which the noise variance at the output terminal of the radar's receiver is cable to infered from the amplitude of the noise at the video terminal of radar. As the result, a way is acquired which reasons out the actual SNR(signal noise ratio) at the output terminal of the radar's receiver from the pure noise and the mixture of echo wave with noise sampling respectively at the video terminal of radar. |
