This book is divided into 4 major parts: the first part deals with radar overview@ radar range equation and radar detection in interference; the second part covers the different radar environment@ such as clutter@ target reflectivity@ etc.; the third part focuses on radar subsystems@ such as antennas@ transmitters@ exciters and signal processor; the fourth part discusses radar signal processing@ Doppler processing@ radar imaging and tracking. Appendices on Maxwell's equations and decibel notation are given. Author(s) Mark A. Richards@ James A. Scheer@ William A. Holm
