Abstract
A retrodiction tracker and related techniques and system are described. The technique extends the track range of an inbound target, initially detected with a low signal-to-noise ratio (SNR) (or initially detected with signals having a low probability of detection) to that of an outbound target where the low SNR detection is being associated with a confirmed, established, track. Retrodiction and backward propagation are being combined with historical plot-to-track association to significantly enhance the tracking capability of a radar.
