A structure which a makes use of both Radar and Electronic Support tools is known as Low Probability of Intercept.Evading identification by ES receiver is the main aim behind the LPI radar.Features like frequency variability, low power, and wide bandwidth lend the property of Low probability of Intercept to the emitter making it undetectable by passive intercept devices like electronic intelligence receivers, radar warning, and electronic support.Novel signal processing methods are needed for identifying LPI radar waveforms.To retrieve meaningful information from the fed signal, Higher Order Spectral Analysis algorithms are utilized.Bispectrum, Bicoherence and Trispectrum techniques comprise the methodologies.For every LPI signal, the images generated by the algorithms are distinct and mean to be identifiers.
