Low probability of intercept (LPI) radars have the property of low power, wide bandwidth, frequency variability or other design features to make them difficult to be detected or identified by passive intercept receiver devices such as radio engineering complexes (RTK). One of the possible solutions to this contradiction is the measurement of time parameters using algorithms for morphological processing of the results of bilinear time-frequency distributions, for example Choi–Williams distribution. The purpose of the article was to provide the possibility of automatic estimation of signals time parameters in conditions of low SNR (less than 0 dB) using algorithms for morphological processing of the time-frequency distribution results.
