Abstract

The Defense Research and Development Canada establishment located at Valcartier has an ongoing project to improve the detection capability of a optical surveillance system presently used by the Canadian Forces, To improve the detection capabilities of the system, we demonstrated and tested a new Range-Doppler imager specialty adapted to the existing infrared imaging system to provide information gathered by the radar to be fuse with the infrared image. Operating in W band (92-94 GHZ), the range resolution of the radar is better than 40cm for a maximum range of 2km. To obtain the Doppler signature of the scene, the radar is mounted on a 1.5m rail directed attached to the cameras pan-and-tilt. To produce the range-Doppler image, the radar is moved on the rail at constant speed. As the motion of the radar is highly linear, no correction is required in the range-Doppler processing to obtain a well focused image. The field of view of the radar is matched to the infrared camera one to facilitate the fusion process.
