Abstract: A method of mitigating vibration in a radar system on a moving platform includes obtaining received signals resulting from reflections of transmitted signals by one or more objects in a field of view of the radar system. The received signals are a three-dimensional data cube. The method also includes processing the received signals to obtain a first three-dimensional map and second three-dimensional map, estimating the vibration based on performing a first detection using the second three-dimensional map, and cancelling the vibration from the first three-dimensional map to obtain a corrected first three-dimensional map. A corrected second three-dimensional map is obtained by further processing the corrected first three-dimensional map; and a second detection is performed using the corrected second three-dimensional map.

Abstract: A vehicle, radar system of the vehicle and method of operating the vehicle. A transmit antenna transmits a radio wave and a plurality of receive antennae receive echo radio waves from an object receptive to the transmitted radio wave, wherein the echo radio waves includes short-range interference. A processor generates a plurality of radar data arrays for the return signals, wherein each radar data array represents the return signal received at a corresponding receiver antennae, estimates an amount of short-range interference present in the return signal of each radar data array, subtracts the estimate of short-range interference from each of the radar data array to obtain a plurality of clutter-free radar data arrays, and detects the object using at least the plurality of clutter-free radar data arrays. A navigation system navigates the vehicle based on the detection of the object.
