A Countercept System Simulator
Abstract
In order to best utilize a previously reported timeseries analyzer in the computation of countercept probability ( the time-dependent probability of asynchronous countermeasures interception) a system simulator has been developed. This device simulates in real or scaled time the output of any given intercept receiver working against any given transmitter. The simulator takes into account all significant parameters - antenna patterns and rotation rates, transmitter power, receiver sensitivity, receiver bandwidth, receiver scan band and scanning rate, the position of the signal frequency in the receiver scan band, the nature of the transmitted signal (e.g. , pulse width and pulse repetition frequency), the nature of the indicator and its coupling to the operator or other decision element (e.g., the minimum number of pulses required for the recognition of a pulsed signal or the minimum duration of signal recognizable as a communication), the statistical variation of receiver threshold introduced by the presence of a human operator, and the attenuation introduced by the propagation path (i.e., the effects of range and elevation).The simulator has been completed and has been used in conjunction with the analyzer to solve one: problem in receiver system design. It is hoped that the problem solving program can be greatly expanded and that the computational facility can be made accessible to other activities.
