Abstract : Interception of radar signals is analyzed. The waveforms of interest are the Linear Frequency Modulation (LFM), the Phase-Coded (PC) and multicarrier (MC) waveforms. The problematic is to perform detection with real-Time requirement and the possibility to integrate on the longest pulse width (LFM). The well-known ambiguity function is proposed as quadratic time-frequency detector which is able to help waveform recognition among the analyzed set of waveforms. Its detection performances are evaluated and some estimators are proposed to facilitate the intrapulse estimation step.
