Radar Image Simulation Project: Development of a General Simulation Model and an Interactive Simulation Model, and Sample Results.
Abstract
This document reports the results of a radar image simulation study performed at the Remote Sensing Laboratory, The University of Kansas, Lawrence, Kansas. The work was sponsored by the U.S. Army Engineering Topographic Laboratories, Fort Belvoir, Virginia. The purpose of this study was to develop radar image simulation and feature extraction techniques. A general model for simulating radar imagery is developed. This model is applicable to both SLAR (Side-Looking Airborne Radar) and PPI (Plan Position Indicator) radar system image formats. It can produce simulations from both flat and mountainous terrain. The model requires as input a completely specified digital ground truth data base. The radar reflectivity data calculated for each image simulation can be determined from a variety of input data sources. The results presented in this document have all been produced using for input reflectivity data, empirical radar backscatter data from a large agricultural/soil moisture data bank available at the Remote Sensing Laboratory. Also reported is a technique for automating feature extraction, creation of data bases, and interactive radar simulation. A model is developed which incorporates an image analyst (human) in the decision process as the computer simulation program runs. Automatic pattern recognition software is used to pre-process the data base and the interpreter/simulator is given the flexibility to specify or alter previous specifications in real-time in synthesizing the radar image.
