Noise radar Interception using the principle of signal matched-phase
A noise radar transmits non-sinusoidal signals which are ultra-wideband and continuous. Theory and experiments show that the noise radar has excellent properties of low probability of interception (LPI). In electronic countermeasure (ECM), the LPI feature of the noise radar brings great challenges to the radar interception. This paper presents a method for noise radar signal detection, based on the principle of signal matched-phase. At the same time, an improved signal matched-phase algorithm is presented, using a posteriori Wiener filter. The improved algorithm reduces the impact of background noise fluctuation. The simulation result shows that the method can considerably improve the signal-to-disturbance power ratio (SDR) and increase the probability of intercepting the noise radar signals.
