Digitizer Performance under Conditions of Linear and Circular Antenna Polarization.

Abstract

The report describes the test methods employed and the results obtained during a test and evaluation that was conducted to determine digitizer performance under conditions of linear and circular antenna polarization. Technical tests were conducted to determine system performance for conditions of linear and circular polarization of the NAFEC ASR-5 Antenna. The tests were performed for inputs derived from permanent echoes, small test aircraft, and test targets within weather clutter. It was concluded that a significant increase in target detection within weather clutter was achieved when employing circular polarization, with little degradation in detection of targets within a clutter-free environment. In most cases the number of false targets within a weather clutter environment was reduced when employing circular polarization. Therefore, improved performance of a radar processor was achieved when employing circular polarization under conditions of weather clutter returns. (Author)
