In this paper, we present a contour based path planner for Unmanned Aerial Vehicles (UAVs).We make use of efficient algorithm to compute a stealthy path line with desired attributes in radar prone environments. The algorithm is employed to estimate the risk cost of the navigational space and generate an optimized path based on the user-specified threshold(More)
Traditional approaches to AUV collision avoidance involve the adaptation of COTS electronic scanning sonars that have been designed for applications where low power is not a consideration. This has an adverse impact on the endurance and performance of the AUV. The navigation and obstacle avoidance processing is typically performed by the vehicle control(More)
