Collision and Obstacle/Terrain Avoidance Warning System (COTAWS) Multifunction Sensor Study.
Abstract
Norden, with the cooperation of the United Aircraft Research Laboratories, compared three microwave radars and one CO2 laser as obstacle detection radars. The test procedure, the data taken, and a discussion of the results of these comparative tests is provided in this report. The microwave radars included one Ku-band amplitude monopulse radar, one Ku-band phase interferometer radar, and one millimeter (70 GHz) radar. The laser was pulsed coherent CO2 laser radar. The obstacles included wires, poles, towers, buildings, and other hazards to low-level flight. The CO2 laser radar detected all hazards to low-level flight including Army field wire at up to 60 deg off normal to the laser radiation. The millimeter radar could detect most hazards to low-level flight but could not provide the same wire detection capability as the laser. The Ku-band radars provided detection of only the large obstacles such as buildings and large towers. (Author)
