This volume contains papers from three sets of tutorial covering mathematics "Topics in Harmonic Analysis with Applications to Radar and Sonar", physical aspects of scattering "Sonar and Radar Echo Structure", and engineering modelling and processing of the phenomena under consideration "Theory of Remote Surveillance Algorithms". In addition, the famous technical report by Calvin H. Wilcox "The Synthesis Problems for Radar Ambiguity Functions" is published here for the first time.
