A Computer Program for Computation of Radar Detection Ranges on a Constant-Altitude Target in Various Environments.
Abstract
In this report a computer program which plots the signal strength of a constant-altitude target over the sea surface is described. The signal strength is plotted, as a function of range, normalized to the signal-to-noise ratio required for a given probability of detection and probability of false alarm in the presence of receiver noise only. The range at which this S/N ratio is obtained in the absence of multipath effects, and when the signal competes only with receiver noise, is defined as the free-space range. To examine the detection range of a target in the presence of clutter and jamming signals, a new threshold is computed which is equal to the ratio of the total noise power (jamming plus noise) to the receiver noise power. This program was originally developed by Blake. In this report, modifications to the program to include MTI and doppler filtering are described. A program listing and example computations are included. (Author)
