Classical Analysis Methods for Designing and Developing Downlooking Radars

摘要

This report describes analytical methods for characterizing the distributions ofsurface clutter as observed by downlooking radars over spherical planets, taking the classical, pencil and paper, methods of analytic geometry and calculus as far as possible before turning to computer based numerical evaluations. General expressions describing surface clutter power distributions in range and range-rate coordinates are developed in closed form and evaluated for several low PRF, phased array configurations. Information contained in this document formed the subject matter for a series of eight lectures at Rome Laboratory, under this contract, to relative newcomers to the study of clutter limited radar. With the classical analysis tools, they were able to quickly obtain results which compared favorably with those from elaborate simulations evolved by teams of experts over periods of many years.
