Radar detection and tracking systems

Book Reviews radar applications are described including radar for airborne navigation, terrain avoidance, altimetry and weather avoidance. Radar beacons, instrumentation radars and radar astronomy are also mentioned. The material in this book was used by the author in a one-week short course at UCLA. For this reason it is not as detailed as the usual textbook and therefore should be of interest to the practicing engineer desiring a knowledge of radar systems with readily applicable methods for calculation. Problems, along with answers, are given for six of the eleven chapters. FORTRAN computer programs are included for the computation of the probability of detection for a target whose radar cross section DAVTD SCHULTZ fluctuates and for the cumulative probaDepartment of Mathematics University of W’i8COn8in bility of detection.

conservation of energy, conservation of linear momentum, and conservation of angular momentum. Moreover, the discrete dynamical equations have the same form under fundamental coordinate transformations. In addition, the author shows that the classical Einstein energy equation E = rncp can be established discretely, with no need for continuous physical concepts. This book describes a completely arithmetic approach to basic nonlinear phenomena. This arithmetic approach coupled with the ability of the computer to do high speed arithmetic is a mathematical simplification that may prove to be of greater value than the more traditional sophisticated methods.
