Multi-function micro-radar for mini-UAV
Abstract
This proposal seeks to explore the potential of multi-channel radar on a very small and versatile platform, i.e. a mini UAV, by exploring several innovations:1) the extension of a linear Digital Beam Forming array (such as the TNO AMBER DBF radar) to an omnidirectional array. This in itself would already provide a big advance in coverage and flexibility, as it provides full 360?? access and multi-functionality, without the need for slow, inflexible, and bulky rotating antennas, or multiple separate antennas.2) exploiting the versatility of the small platform, which can easily go from steady linear flight, to hovering, rotation, or vertical motion. Thus, it becomes possible to quickly adapt the platform motion to the function of the radar at a particular time, and in fact to jointly optimize the platform maneuver and radar operation mode for a specific task.3) using the radar to aid and improve navigation: while GPS may provide absolute position, small inertial sensors that can provide attitude are quite inaccurate, and experience drift. A 360?? radar can enhance motion information by providing good estimates of attitude, velocity, and altitude. Furthermore, the radar can provide IMU drift elimination in GPS denied-environments.
