The proposed adaptive array beamformer is to be considered as a component which will be added to an existing radar system with minimal change in the overall configuration. Measurements were taken under conditions representative of the environment in which an HF system must operate. Specifically, one-hop backscatter signals generated by an FMCW transmitter format were received in the presence of relatively high noise and interference levels. Adaptive beamforming techniques are ideally suited to these conditions and can provide time variable null-tracking of both the frequency and spatial direction of arrival of interference sources.
