Abstract : The objective of the program is to produce separate antenna two-way coverage patterns for the close-in and long range capabilities of the terminal radar system. The feedhorn geometry of the ASR-5 antenna was modified by adding a separate receive only feedhorn and polarizer. The close-in coverage was obtained by transmission on the normal (low) beam and reception on the second (high or tilted-up) beam. The long range coverage was obtained by both transmission and reception on the normal beam. This program was divided into two phases. Phase I involves the work performed to determine the feasibility of a dual feedhorn configuration to be employed with an ASR-5 antenna. Phase II concerns the design and test of the hardware to be delivered to the FAA for evaluation with an ASR-5. (Modified author abstract)
