Comparative tests between TIESPAD and SPA-66 radar display
Abstract
Comparative tests were run between TIESPAD and the AN/SPA-66, a product-line shipboard PPI display. The Time Encoded Spatial Display (TIESPAD) is a radar video processing unit designed and built by Naval Ocean Systems Center. It is a 512 x 512 resolution scan converter with additional processing and memory to accomplish the time compression task using solid-state memory; the output is displayed on a TV monitor. The tests were run using a combination of recorded live radar video and target simulator video. The tests were made to compare a radar operator:s ability to detect targets in random noise, track a single target through heavy clutter, and track multiple targets. The following conclusions were reached: (1) Tracking in clutter is more efficient on TIESPAD than on SPA-66; (2) Detection efficiency is approximately equal on each; (3) Perceived signal-to-noise ratio is degraded on TIESPAD; (4) Higher resolution scan converter is desirable; and (5) Operator controls need improvement.
