Quiet Radar Processor Analysis by Covariance Matrix Transformations.

Abstract

The MICOM Quiet Radar program is a multi-year exploratory development effort to build and test a short-range air-defense system radar with Anti-Radiation Missile (ARM) immunity. By transmitting a low-power, bi-phase modulated, continuous-wave waveform in conjunction with ultra-low sidelobes antenna and a frequency-agile carrier frequency, it is possible to reduce ARM lock-on capabilities to ineffective ranges. The objective of this effort was to determine probability of detection for a given false alarm rate for a candidate Quiet Radar processor by performing covariance matrix transformations. The analysis included range cell averaging CFAR. Results were obtained for two possible configurations of the Quiet Radar processor. The results are given as plots where the probability of detection in each frequency cell is shown for various probabilities of false alarm and CFAR range cell window widths. The analysis has verified previously determined CFAR losses and shown that processor performance is dependent on the low pass filter used for noise reduction. (Author)
