Abstract: A device includes: a millimeter-wave radar sensor circuit configured to generate N virtual channels of sensed data, where N is an integer number greater than one; and a processor configured to: generate a 2D radar image of a surface in a field of view of the millimeter-wave radar sensor circuit based on sensed data from the N virtual channels of sensed data, where the 2D radar image includes azimuth and range information, generate a multi-dimensional data structure based on the 2D radar image using a transform function, compare the multi-dimensional data structure with a reference multi-dimensional data structure, and determine whether liquid is present in the field of view of the millimeter-wave radar sensor circuit based on comparing the multi-dimensional data structure with the reference multi-dimensional data structure.

Abstract: An apparatus includes interface circuitry configured to receive data indicating a measurement signal of a radar sensor. The apparatus further includes processing circuitry configured to determine a rate at which the measurement signal crosses a predefined value based on the data and determine presence of at least one of an interference signal and a target motion in a field of view of the radar sensor based on the rate.

Abstract: A radar system comprising a radar sensor is provided. The radar sensor comprises an antenna configured to emit a radar beam towards a predefined region. The radar system further comprises a reflector spaced apart from the radar sensor and configured to redirect at least part of the radar beam towards a target region different from the predefined region. The reflector is further configured to redirect a reflection of the radar beam originating from the target region onto the radar sensor.

Abstract: In accordance with an embodiment, radar system includes a radar sensor having a first antenna configured to emit a radar beam towards a predefined region. The radar system comprises a reflector spaced apart from the radar sensor and configured to redirect at least part of the radar beam towards a target region different from the predefined region. The radar sensor comprises a second antenna configured to receive a reflection of the radar beam originating from the target region.
