Abstract : The objective of the integrated high-frequency antenna system (IHFAS) program is to provide a simultaneous operation (SIMOP) capability for the P-3 hf communication system. This capability will be provided for the P-3C, which will incorporate the higher hf transmitter powers and Link 11 data capability of A-NEW. A technique was developed to optimize transmit filters. This technique enables analysis of system parameters to determine detailed requirements for an optimum high-level transmit filter. A series of tests were performed on the AN/ARC-132(V) hf transceiver to aid in evaluating it as a SIMOP radio. General performance tests were conducted in accordance with applicable portions of MIL-STD-449C. In addition, external intermodulation, spurious voltage, and spurious impedance measurements were made. (Author)
