This paper presents a new approach to sonar pulse detection. The method uses chirp rate estimators and algorithms for adaptive threshold, commonly used in radiolocation. The proposed approach allows detection of pulses of unknown parameters, which may be used in passive hydrolocation or jamming detection in underwater communication. Such an analysis is possible thanks to a new kind of imaging, which presents signal energy in function of chirp rate. The proposed method rely on chirp rate
