Estimation of object location from short pulse scatter data

IVe present, an efficient algorithm for computation of the maximum likelihood estimate of the location of a known target, from short. pulse scatter data. The algorithm consitutes a three step procedure: (i) data filtering. (ii) time-domain backpropagation. and (iii) coherent. summation and consists of a number of projection and backprojection operations int,egrated in a tomographic scheme. .A computer simulation is included for illustration purposes and relevant. applications in radar target identification and buried object detection are discussed.
