A key question in SAR-aided search is the relative utility of L-Band versus P-Band data. A continuing study is underway using target data collected by the NASA Search and Rescue Mission. This paper presents the most recent results of the investigation, including Navy P-3 SAR data at L-Band and JPL SAR data at L-band and P-band.
