Transmit codes and receive filters for radar

This article's main goal is to show how to design the receive filter (including its length) and the transmit code sequence via the optimization of a number of relevant metrics considered separately or in combination. Several numerical studies are given to illustrate the performance of the presented designs. Compared with most of the previously published works on the subject, the present contribution is more coherent as well as more complete, and yet the approach taken here is generally simpler both conceptually and computationally. Finally, weremark on the fact that while the focus is on radar systems, for the sake of being specific, the theory and design methods presented should be useful to several other active sensing applications, such as sonar, nondestructive testing, seismic exploration, and biomedical imaging.
