Abstract: A system and rack includes an antenna subsystem having a preexisting processing pipeline that receives radio frequency returns and an upgraded signal processing pipeline that performs detection processing for the antenna subsystem. The upgraded signal processing pipeline couples to the preexisting processing pipeline. The upgraded signal processing pipeline includes sampling converters to sample the radio frequency returns of the antenna subsystem, field-programmable gate array devices to generate detection data of the radio frequency returns at full-bandwidth and full-range of the antenna subsystem, graphics processing units to apply algorithms to the detection data of the radio frequency returns, and a signal processor configured to perform operations on the sampled radio frequency returns. The operations can include sampling returns, down-converting sampled detections, filtering detections, digitizing radio frequency returns, and applying algorithms to generate output data.

Abstract: Aspects of the invention provide improvements to analyze data collected by a radar system. One of the systems includes a phased array module configured to transmit a sequence of pulses to an environment according to a pre-determined pattern. A data analysis system constructs an image based on returned signals from a single point received by the phased array module, and determines one or more characteristics of a target object in the environment based on the image constructed from the returned signals from the single point.

Abstract: A computation machine comprises a first data buffer, a second data buffer, a correlator neuron and a neuron controller. The first data buffer stores a multi-bit input data value. The second data buffer stores a multi-bit weight value. The correlator neuron includes multiple single-bit digital dendrites, each of which inputs, at a point in time, one bit of the input data value from the first data buffer and one bit of the weight value from the second data buffer. The correlator neuron generates an output indicative of a correlation between the buffered input data value and the buffered weight value. The neuron controller provides the weight value to the correlator neuron circuit, and controls one or both of the first data buffer and the second data buffer to cause a shifting, relative to each other, of the input data value and the weight value.

Abstract: Aspects of the invention provide improvements to electromagnetic and other wave-based ranging systems, e.g., RADAR or LIDAR systems, of the type having transmit logic that transmits a pulse based on an applied analog signal. The improvements are characterized, in part, by a SERDES having a serializer (a/k/a a “transmit side”) that is coupled to the transmit logic. The serializer has (i) an input to which a pattern on which the pulse is based is applied and (ii) an output from which a serialization of the pattern is applied to the transmit logic. The improvements are further characterized in that the SERDES has deserializer logic (a/k/a a “receive side”) that is coupled to receive logic and that deserialize a received “analog” signal containing possible reflections of the pulse.
