Adaptive Beamforming
Adaptive processing has the potential to significantly enhance the target detection and tracking performance of OTH radar systems because of the statistically structured or “colored” nature of HF disturbance signals often encountered in practice. Indeed, the application of robust spatial, temporal, or joint space-time adaptive filtering techniques may typically be expected to mitigate strong disturbances such as clutter and interference more effectively than conventional (data-independent) processing. This chapter is concerned with the application of adaptive beamforming to improve the output useful-signal-to-disturbance ...
