Abstract : The tracking apparatus uses multi-processor modules for predicting in real time the parametric behavior of radar signals to be jammed, as part of an electronic countermeasures system. The tracker system is partitioned into three board (module) types - (1) a subsystem request handler, which transfers data from system buses to the tracker system, (2) one or more multi-processor modules (each including a parameter memory and three arithmetic units with micro-sequencers) which does the actual track operation yielding the prediction data, and (3) a vector buffer module, which transfers the completed prediction data onto the buses for the receiver and transmitted. The system computer transfers to the tracker the necessary parameter information (latest time of arrival, threat type (stable, stagger, agile, etc.), angle of arrival, etc.) and initiates a track loop. Central to the operation of the trackers is the parameter memory which is divided conceptually into two main parts: pattern and parameters. The parameter portion of the memory is subdivided into blocks, each dedicated to a particular threat. The defining parameters for that threat are passed from the CPU just before a tracker is started.
