Abstract
Radar Emitter Signal recognition is one of the key procedures of signal processing in Electronic Warfare (EW) Receiver. As there is an intense growth in the activities of modern Electronic Warfare, advanced radars are increasing and becoming main component of radars gradually. These modern radars called Low Probability of Intercept (LPI), use different complex waveforms to mask their presence from the enemy while accomplishing their mission. These waveforms cannot be detected by the use of traditional recognition algorithms and methods thus posing a major challenge to the Electronic Warfare designer. This paper presents simulation of different types of LPI signals, generation of those signals and development of Time Frequency Algorithm to analyze those signals.
