Robust Adaptive Beamforming for Wide-Band, Moving, and Coherent Jammers via Uniform Linear Arrays

Monika Agrawal and Surendra Prasad

Page 1267.

Abstract:

The problem of providing robustness to the conventional narrow-band uniform linear array configuration so as to handle wide-band and moving jammers is addressed here. This robustness is achieved via the use of derivative constraints in jammer directions. However, since the jammer directions are not known a priori, these constraints are incorporated with a maximum likelihood characterization of the so-called jammer subspace. This formulation does not need to assume the availability of signal-free observations, as stipulated in earlier work. Computer simulation results are presented, which show that the algorithms proposed here yield significantly better performance as compared to the previous algorithms of Gershman et al. [1], [2] and Hung and Turner [3] in a variety of situations required to handle wide-band, moving, and coherent jammers.
