Abstract:
In this paper, we consider the problem of cognitive transmit code and receive filter design for target detection in clutter. Since the previous works have considered clutter statistics to be a priori knowledge, in this paper, assuming unknown clutter covariance matrix, we propose two methods for estimating the parameters of the clutter covariance matrix (both based on secondary data and clutter model), and use them to develop cognitive algorithms for the joint design of transmit code and receive filter. Simulation results demonstrate that the clutter covariance matrix estimation error will lead to negligible performance loss. Moreover, as the number of secondary data increases, the average convergence rate of the proposed algorithms reaches the rate of the known clutter covariance matrix case.
