ASR-9 Processor Augmentation Card Scan-Scan Correlator Algorithms.

Abstract

This report documents the scan-scan correlator algorithms developed for the ASR-9 Processor Augmentation Card (9-PAC) project. The 9-PAC is a processor card that serves as a processing enhancement to the existing ASR-9's post-processor system. It provides increased speed and memory capabilities to the processor, which allows for the introduction of more complex primary and secondary surveillance algorithms. These more complex algorithms improve the ASR-9's system performance by offering decreased false alarms, and increased detection of aircraft. The 9-PAC scan-scan correlator, also known as the tracker, consists of three basic processing tasks: initialization, input/output, and the actual tracker. The tracker can be broken down further into four main processing functions: report-to-track association, report-to-track correlation, track update, and track initiation. These four 9-PAC functions are the same as in the original ASR-9 processor, but with different algorithms. Each of these functions is addressed individually in this report and is further broken down into sub-functions for more detailed discussion. In addition to the algorithms, the system requirements are reviewed, and the chosen data structures for implementing the algorithms are detailed
