Detection of Radar Signals in Conditions of Full Prior Information when Using Stochastic Signals for Probing

摘要

Probabilistic characteristics of coherent detection of reflected signals with the fully known parameters when using stochastic soundings radio signals are determined. Analytical expression for probability density of decision statistics for the cases of presence at detector's input of reflected signal only, interference only, and both signal and interference is obtained. Dependency of false alarm probability on threshold ratio and dependency of hit probability on signal-to-interference ratio for different values of bandwidth-duration product of stochastic signal are computed. A family of radar detection performances characteristics for fixed bandwidth-duration product and different values of false alarm probability is calculated.
