Present State and Ways of Passive Anti-LPI Radar Implementation

Radar of small range with Low Probability of Intercept (LPI radar) and means of secure communications of noise and quasi noise type attract now attention of engineers. Some examples of LPI radar were presented The emission stealth can be provided by using noise type signals with large time-bandwidth product. However, one should take into account the limited stealth capabilities of noise type emissions. Unknown prolonged noise signal with continuous power spectrum on the stationary white noise background can be effectively detected using its noncoherent integration using appropriate multichannel detector.
