Description<\/strong><\/h2>\n\n\n\n

In 1974, the United States Navy awarded the first contract for the AN\/BQR-23 towed array processor. Developed by Spectral Dynamics Corporation, this processor was specifically designed for use with the AN\/BQR-15 towed array sonar system<\/a><\/strong>.<\/p>\n\n\n\n

The AN\/BQR-23 provided at least 64 simultaneous Low-Frequency Analysis and Recording (LOFAR) channels in real time. LOFAR is crucial for detecting low-frequency sounds in the ocean, which can indicate the presence of other vessels or underwater activities. The processor featured visual displays in both LOFAR and frequency-azimuth formats, allowing operators to analyze sonar data more effectively.<\/p>\n\n\n\n

An improved version, the AN\/BQR-23A, introduced bearing-interpolation trackers. These trackers smoothed bearing data, improving the accuracy of target detection and tracking. The multichannel digital signal processing capabilities of the BQR-23A were a major improvement over similar systems on U.S. strategic and attack-class submarines at the time.<\/p>\n\n\n\n

In the AN\/BQR-15 SPALT\u00a09080 it was replaced by the Rockwell AN\/BQQ-9 TASPE (Towed-Array Signal Processing Equipment)<\/a><\/strong>.<\/p>\n\n\n\n

Note: Spectral Dynamics Corporation, founded in 1961, specialized in designing and manufacturing audio-range signal analysis instruments and systems. The company was later acquired by Scientific Atlanta of San Diego..<\/p>\n\n\n\n
