Collision Avoidance Radar for UAV

A critical sensor characteristic for obstacle awareness and avoidance for UAV is assessed with the compliance of the equivalent level of safety regulation. Based on the assessment of the obstacle awareness and collision avoidance sensor, the small-sized, light-weighted radar sensor is proposed for the suitable candidate in meeting with the system requirement as well as operational requirement of smart unmanned vehicle. The conceptual radar design result is also presented with the design parameters and the radar detection and avoidance procedure are simulated with the probability of obstacle detection and the avoidance scenarios. As a result of performance assessment for obstacle detection performance, probability of detection is more than 90% at the given required detection range. The performance of collision avoidance mode is also simulated based on the various radar range and range-rate data in the four different flight scenarios
