Abstract: A system and method for generating alert signals in a detection system is described. The system compares data extracted from signals received via receive antenna beams with stored scenarios and determines whether to generate an alert signal based upon the results of the compare operation. The comparison of data extracted from received signals with stored scenarios can be accomplished by using one or more latches to process the extracted data from the received signals. In one embodiment, raw detections are pre-processed to generate so-called field of view (FOV) products. The FOV products are then provided to a tracker. In another embodiment, rather than pre-process the raw detections, the raw detections are instead provided directly to a tracker which processes the raw detections to provide products including, but not limited to, relative velocity and other parameters.
