Methods of Wideband Signal Design for Radar and Sonar Systems.

摘要

The radar problem is generalized to wideband signals and receivers. This generalization necessitates consideration of a wideband ambiguity function and of distributed targets. System design methods,using newly-discovered properties of the wideband ambiguity function,the trajectory diagram,and computerized clutter suppression techniques,are established. The application of these methods,combined with distributed target and accelerating target considerations,reveals signals that are optimally tolerant to doppler,acceleration,and distributed target effects. These signals are compared with those used by several species of bats. (Author)
