A blockage detection system and methods for use in a radar sensor such as a side object detection (SOD) sensor in an automotive radar system are described. The blockage detection system and method operate in systems including two or more radar sensors having overlapping field-of-views (FOVs). The blockage detection system includes a storage in a first radar sensor having stored therein a tracked object list including detections/tracks for one or more targets made by a second radar sensor and a processor for adjusting an overlap zone associated with the first radar sensor based upon an estimated mounting angle of the first radar sensor. The system further includes a processor coupled to the storage and processor configured to identify one or more relevant detections/tracks from the tracked object list using the adjusted overlap zone and a blockage detection processor configured to receive the relevant detections/tracks from said processor and configured to compare the relevant detections/tracks to detections/tracks for one or more targets made by the first radar sensor.

The invention provides a compact, high-frequency, transmit and receive millimeter-wave radar sensor device, system, and method of use. The sensor can operate at a variety of distances, speeds, and resolutions depending on the hardware components selected in a given implementation. The hardware and software architecture is generic and can be tailored to required applications.
