Modeling and performance of HF/OTH radar target classification systems

The effects of a class of multipath propagation channels on the performance of a radar target classification system are considered. A Rician frequency-selective fading channel model is used to characterize the effects of the multipath propagation medium and evaluate the performances of radar target classification systems. The performances of classification algorithms that use relative amplitude, relative phase, and absolute amplitude measurements as features are investigated. Performance estimates of the various classification algorithms for interesting sets of channel parameters are obtained by means of Monte Carlo simulations
