Abstract: Body text indent—does not have paragraph numbering turned on. Not needed in the Abstract. An integrated circuit device includes a digital sine wave generator configured to produce portions of a digital sine wave, a combiner circuit configured to output each of the portions of the digital sine wave combined with a respective calibration code during operation in a post-production dynamic test mode, a digital to analog converter (DAC) configured to output an analog sine wave based on the output of the combiner circuit, and a test analog to digital converter (ADC) including an input terminal directly connected to the output of the DAC, and configured to generate a second digital sine wave based on the analog sine wave.

Abstract: A radar system, apparatus, architecture, and method are provided with a transmitter that produces a plurality of distinct FanTOM signals that are transmitted as N RF-encoded transmit signals in an overlapped fashion such that the pulse repetition interval and frame length are kept short; a receiver that processes target return signals reflected from the N RF-encoded transmit signals with a mixer to produce an IF signal which is filtered with one or more notch filters clocked with a sampling clock frequency to control harmonic notch frequencies to suppress transmitter spill-over and close-in self-clutter interference, thereby producing a filtered IF signal that is converted to a digital signal with an analog-to-digital converter that is clocked with the sampling clock frequency; and a radar processor that processes the digital signal to generate a range spectrum comprising N segments that correspond, respectively, to the N RF-encoded transmit signals.
