PADE APPROXIMATIONS FOR DETECTABILITY IN K-CLUTTER AND NOISE

The Pade approximation (PA) method is used to analyze the detection pe rformance of single and multiple pulse radar systems operating in K-di stributed clutter and thermal noise. Simple approximations for false-a larm and detection probabilities are obtained, using lower order momen ts for the detection decision statistic. Both envelope and squaring de tector laws are considered, with noncoherent integration, for independ ent and correlated K clutter. The target is assumed to be pulse-to-pul se Rayleigh fading. The methods are a substantial application of the P A methods we have recently published.
