Description of Radar Correlation and Interpolation Algorithms for the ASR-9211 Processor Augmentation Card (9-PAC)

摘要

The ASR-9 Processor Augmentation Card (9-PAC) provides increases in processing211u001espeed, memory size, and programming ease when compared with the existing ASR-9 211u001eArray Signal Processor (ASP). These increased capabilities allow for some of the 211u001eknown problem areas of the ASR-9 to be addressed with improvements to the 211u001eexisting radar and beacon processing algorithms. This report describes the 211u001eimprovements to the radar Correlation and Interpolation (C&I) process, as well as 211u001eproviding implementation details for the C language version of the entire C&I 211u001efunction. Sections 2 and 3 of this document provide background information on the 211u001eASR-9, 9-PAC, and C&I requirements. Section 4 describes the subset of C&I 211u001ealgorithms that were ported to the C language with only minor enhancements. 211u001eSection 5 describes the new geocensoring and adaptive thresholding algorithms. 211u001eSection 6 supplies details of the two-level weather processing algorithms, which 211u001eare not part of the C&I processing per se, but are grouped with C&I because the 211u001eweather data is embedded in the radar data stream. Sections 7 and 8 describe the 211u001eVariable Site Parameters (VSPs) and Performance Monitoring/Alarm outputs. Section 211u001e9 summarizes the work done to date and discusses possible future enhancements. 211u001eLastly, appendices contain algorithm flowcharts, report formats, and constant 211u001etables.
