Improving the probability of detection inside the intersection area of two-radar systems based upon scan-to-scan processing, scan rate modulation, and probability fusion rules

This paper discusses the probability of detection enhancement at the fusion area scanned by two radars. The improvement is implemented by three techniques, scan rate modulation, scan-to-scan processing, and applying the probability of detection rules (AND, OR) to make a decision. The simulation results reveal that using AND rules with precalculation of the threshold is better at enhancing the probability of detection and reducing the probability of false alarm. Furthermore, scan-to-scan processing has a considerable influence on reducing false alarms. Moreover, scan rate modulation increases the probability of detection and maintains the probability of false alarm within a permissible limit.
