Abstract
The Canadian Forces are updating the acoustic processing capability on the CP-140 Aurora Aircraft. Included in this effort is the delivery of the MVASP (Modular VME Acoustic Signal Processor) system to replace the older OL-5004/AYS acoustic processor. MVASP includes the capability to process fields of sonobuoys as an integrated Multistatic Active Sonar. An upgraded DIFAR (Directional Frequency Analysis and Recording) buoy (AN/SSQ-573) with multistatic performance enhancements is being developed. DAEPM (M) requested that DRDC Atlantic investigate the bearing performance of the AN/SSQ-573 sonobuoy. A contract was awarded to compare the performance of the AN/SSQ-573 DIFAR sonobuoy relative to two production DIFAR sonobuoy models (AN/SSQ-53D(3) and AN/SSQ-53F). Detection performance and bearing accuracy were examined for medium- to low-SNR simulated echoes at the Canadian Forces Maritime Experimental and Test Ranges. The contract was successful in that it provided insight into the relative performance, though some questions were raised, related to bearing bias, which could not be fully investigated within the scope of this work. This report summarizes the contracted work performed while the results were provided to DRDC Atlantic for further analysis and inclusion in a DRDC Atlantic Technical Memorandum.
