摘要：

In many radar and sonar applications, the narrowband signal assumption is not respected. To preserve good performance detection and/or parameter estimation for wideband signal, it is necessary to develop appropriate signal models and processing algorithms. More specifically, the range migration of the target during the processing interval induces a coupling between range and Doppler that is not taken into account by standard algorithms such as the Capon and APES methods. In this paper, we present a modified and enhanced version of the Capon and APES algorithms for a wideband signal model. These two algorithms are adaptive filters designed for spectral estimation. Performance of the wideband-Capon and the wideband-APES algorithms are studied via numerical simulations.
