Editorial Reviews

Based on his own career analyzing radars as part of surveillance, weapons, and traffic control systems, Curry assembles those models for whole-system analysis that he has found most useful in various situations. The key models are coded as Visual Basic for Applications software functions that can be used for radar analysis in Excel workbooks, contained on the 3.5<"> disk. He has simplified some of the models, and tried to indicate where, but reminds readers that they need to be modified for specific applications anyway. He does not expect readers to be radar experts, but to have a general engineering and mathematical background. Annotation c. Book News, Inc., Portland, OR (booknews.com)
