Abstract
This report is a summary of the work performed during 145th European Industrial Study Group on the topic of Simultaneous Transmission and Reception of electromagnetic signals presented by Dstl. We establish that the solution to this problem lies in estimating the reflected signals caused by the outgoing signal. We define the problem mathematically using an integral equation to represent the received signal. From this we derive Cramer-Rao bounds which give lower bounds for the error when estimating the signal based upon error in the calculation of the reflected signal. We perform numerical simulations for a simple example to demonstrate some techniques that can be used in the solving of this problem.
