TYPE TEST OF AN/APS-20A

Abstract

The AN/APS-20A is a high-powered Airborne Early Warning radar system. It is capable of detecting and mapping targets located within the search horizon determined by the airplane altitude. The information thus obtained is reproduced on two PPI tubes within the plane as well as being simultaneously relayed by radio relay equipment to some remote point and being reproduced there. The results of the noise and interference tests on this equipment are covered in this report. They show that both the radiated and conducted noise levels are much too high for use in Naval aircraft. Recommendations are made which give means of reducing the noise to a reasonable level.
