Task-Based Evaluation of Raw Radar Data Compression: A Pre-Registered Study of Where Classical Codecs Fail to Preserve Target Detection, and Why

Synthetic aperture radar (SAR) systems collect raw I/Q echo data at rates that exceed downlink capacity; fielded systems compress onboard with block-adaptive quantization (BAQ/FDBAQ). Proposed replacements, including learned compression, are typically evaluated with image-quality metrics (PSNR, SSIM, SQNR); none measur...
