Issues in adaptive beam former DSP implementation (TS-101) for L-Band multi look space borne SAR

We have taken single and multiple beam formation along with Beams adapted optimally to get required Direction of Arrival (DOA) estimation or directed beam forming. We analyze state of the art criteria for Adaptive antenna, suppressing the interference in directions other than desired. We model the Uniform Linear array (ULA) based on simulations of various adaptive and non-adaptive algorithms. We formulate the array antenna that tries to reduce the error by optimally adjusting the weights. The Uniform Linear Array Antenna as well as Planar Antennas discussed here cover most beam forming aspects and we have suggested ways to improve algorithm and make it fast and less complex. We suggest use of Analog DSP Tiger SHARC T-101 for implementation. An adaptive antenna optimal weight adjustment is discussed here.
