Abstract: This paper presents a method to efficiently characterize a large number of Low Probabilities of Intercept (LPI) signal classes. First, we propose a method to detect the regions of interest. Then, an analytic characterization of the signals Instantaneous Frequency Laws (IFL) is done. The main concept involved in this method is the polynomial phase modelling using the warped version of the High-order Ambiguity Function. Some results will be presented to illustrate the proposed method outlines.

Keywords: high-order ambiguity function, detection, warping operator, LPI RADAR, Electronic Warfare.
