HRR length and velocity decision regions for rapid target identification

摘要

Abstract: Effective theater defense requires rapid target identification with ground sensors. Modern radar performs target recognition and target imaging tasks, in addition to conventional tasks of detection and tracking. New processing techniques, like stepped frequency waveforms and RF hardware are now becoming available and will soon result in lower- cost high resolution rate. Additional feature extraction, namely length and velocity obtained from tracker can be used to design an efficient and a rapid ID after a preliminary recognition is performed. Prior information of these features for critical set of targets can be used to design decision regions for a given SNR value.!13
