What makes this an especially useful book, is the coupling with the MATLAB routines, which are downloaded from the publisher's website. Once on your PC, you can edit them, put your own code into them, integrate them with your other routines, or use them stand-alone. Surprisingly, the download worked exactly as stated in the book, the very first time, without any problems. You are good to go, instantly. The book tells you how to use the downloaded routines, and gives background information on the topic. You can also reproduce the figures in the book, with the routines provided. This is especially useful if you like the graph, but need to adjust it (i.e. edit the routine)to cover your particular problem. If you don't have access to MATLAB, you might like the Richard Curry book "Radar System Performance Modeling", which has radar functions that plug into your Excel spreadsheet as add-in user-defined functions. I have both, and use both, for different applications.
