Abstract:

A simulation technique has been developed to provide the radar engineer with a tool for comparative examination of radar systems and target detection in the presence of look-down clutter. Using a plotting interface such as the Dedicated User Interface System DUIS, an engineer can evaluate proposed radar designs against one another for target detection performance in a precise graphical format. The user is able to select an antenna function from either measured data or derived data under the existing Parametric Antenna Analysis Software PAAS. The antenna platform may be at any designated altitude and velocity with respect to ground clutter scatterers. Entry of an exoatmospheric altitude automatically computes the proper circular satellite orbit velocity and introduces Earth rotation. Target radar echoes at specified ground locations are compared to clutter echoes in the sidelobes as well as the radar mainbeam. Analysis of output date serves as a measure of moving target minimum detectable velocity MDV for the total radar system. Written for analysts with some technical doppler radar and clutter understanding this report leads the engineer through the theory and equations which develop the simulation computer program. Example cases and analyses are given to show program utility and output results.
