Abstract
Results are presented for the evaluation of an adaptive-antenna algorithm designed for the NATO STANAG 4285 PSK (phase-shift keyed) waveform. The algorithm was developed at the Communications Research Centre (CRC) and has been implemented on both the Andrew SciComm HF Adaptive-Antenna Receiving System (HFAARS or An/FRQ-26) and the SED Systems Programmable HF Adaptive Receiving System (PHFARS); the tests reported here were conducted using the Andrew HFAARS. The goal was to evaluate the antijamming capability for groundwave or line-of-sight communications in the presence of various types of jamming signals. Performance of the system was characterized in terms of bit-error rate (BER) versus jamming-to-signal ratio (J/S) under various signal, jamming, and propagation conditions. Under most of the test conditions reported, the algorithm was able to suppress the jamming signals by at least 40 dB.
