Optimum Array Filters for Two-Dimensional Sensor Arrays
Sangil Park, Nasir Udin Ahmed · IEEE Transactions on Geoscience and Remote Sensing · 1987
This communication presents optimum and "absolutely optimum" filtering algorithms for two-dimensional sensor arrays. These algorithms can extract the desired signal, while suppressing an undesired coherent interference. They are derived using a frequency-domain constrained filtering technique, and are relevant to three types of arrays: rectangular, circular, and elliptical. Illustrative examples are also included.
