1. A sparse multichannel array, comprising:

  • a plurality of array elements;

    a plurality of receivers, wherein each receiver in the plurality of receivers is behind a respective array element in the plurality of array elements;

    a Doppler filter bank behind each receiver in the plurality of receivers, wherein respective Doppler bins of the Doppler filter bank have spatial nulls placed at selected angles of undesired interference; and

    a signal processor coupled to respective outputs of the Doppler filter bank, wherein the signal processor is configured to perform nonlinear processing for each Doppler bin.
