Modeling and Performance of HF/OTH (High-Frequency/Over-the-Horizon) Radar Target Identification Systems

Abstract

This report investigates the effect of various channels on the performance of a Radar Target Identification system. Coherent, incoherent, and multiplicative component channel models are developed to synthesize estimation of features. In addition, a frequency-selective fading channel model is developed to observe the effects of multipath propagation on the identification system. A Monte-Carlo computer simulation provides performance estimates of various channels. It is shown that decreasing the frequency band degrades classification performance. It is also shown that given a highly correlated fading channel, classification performance using relative radar cross section (RCS) estimates may approach that of using coherent absolute RCS estimates. Keywords: High frequency, Over the horizon radar, Doppler radar.
