Abstract: Methods for monitoring of performance parameters of one or more receive channels and/or one or more transmit channels of a radar system-on-a-chip (SOC) are provided. The radar SOC may include a loopback path coupling at least one transmit channel to at least one receive channel to provide a test signal from the at least one transmit channel to the at least one receive channel when the radar SOC is operated in test mode. In some embodiments, the loopback path includes a combiner coupled to each of one or more transmit channels, a splitter coupled to each of one or more receive channels, and a single wire coupling an output of the combiner to an input of the splitter.

Abstract: A radar apparatus for estimating position of a plurality of obstacles. The radar apparatus includes a receive antenna unit. The receive antenna unit includes a linear array of antennas and an additional antenna at a predefined offset from at least one antenna in the linear array of antennas. The radar apparatus also includes a signal processing unit. The signal processing unit estimates an azimuth frequency associated with each obstacle of the plurality of obstacles from a signal received from the plurality of obstacles at the linear array of antennas. In addition, the signal processing unit estimates an azimuth angle and an elevation angle associated with each obstacle from the estimated azimuth frequency associated with each obstacle.

Abstract: Data memory protection is provided for a signal processing system such as a radar system in which the data memory is protected with a common set of parity bits rather than requiring a set of parity bits for each memory word as in Error Correction Coded (ECC) memories. The common set of parity bits may be updated as memory words in the data memory are accessed as part of signal processing of one or more digital signals. The memory protection ensures that in the absence of memory errors the common parity bits are zero at the end of processing the digital signals as long as each word in the data memory that is used for storing the signal processing data is written and read an equal number of times.

Abstract: A device includes a circuit board having thereon, a controlling component, a first radar chip and a second radar chip. The first radar chip includes a first radar transmission antenna, a second radar transmission antenna and a first radar receiver antenna array. The second radar chip includes a second radar receiver antenna array. The controlling component can control the first radar chip and the second radar chip. The first radar transmission antenna can transmit a first radar transmission signal. The second radar transmission antenna can transmit a second radar transmission signal. The second radar chip is spaced from the first radar chip so as to create a virtual receiver antenna array between the first radar receiver antenna array and the second radar receiver antenna array.

Abstract: Disclosed examples include a radar system that operates in a first mode and a second mode. In the first mode, the system detects the presence of an object within a threshold range. In response to detection of the presence of the object, the system transitions to the second mode, and the system generates range data, velocity data, and angle data of the object in the second mode. When the object is no longer detected within the threshold range, the system transitions back to the first mode.

Abstract: The disclosure provides a radar apparatus. The radar apparatus includes a transmitter that transmits a first chirp. The first chirp is scattered by one or more obstacles to generate a first plurality of scattered signals. A plurality of receivers receives the first plurality of scattered signals. Each receiver of the plurality of receivers generates a digital signal in response to a scattered signal of the first plurality of scattered signals. A processor is coupled to the plurality of receivers and receives the digital signals from the plurality of receivers. The processor performs range FFT (fast fourier transform) and angle FFT on the digital signals received from the plurality of receivers to generate a first matrix of complex samples.
