This topic is designed by NASA lead agency Ames Research Center to address technologies that would enable a safer and more reliable space transportation capability. NASA is seeking innovative technologies including sensors and communication which expedite launch range clearance. Needed is equipment that will provide real time situation awareness for safe range operation from processing to launch and recovery. Proposed herein is a very small, low cost, high resolution, dual-mode lightweight sensor for remote detection, recognition, and identification of persons and objects that have intruded into areas of the identified range. The dual-mode sensor combines high resolution millimeter radar with high resolution electro-optical sensor. The proposed sensor is low cost and compact, meeting size, weight, power, and stability requirements for a variety of platforms, including unmanned vehicles, buoys, and high altitude air ships.
