In an embodiment, a method includes: transmitting a plurality of radar signals using a millimeter-wave radar sensor towards a target; receiving a plurality of reflected radar signals that correspond to the plurality of transmitted radar signals using the millimeter-wave radar; mixing a replica of the plurality of transmitted radar signals with the plurality of received reflected radar signals to generate an intermediate frequency signal; generating raw digital data based on the intermediate frequency signal using an analog-to-digital converter; processing the raw digital data using a constrained L dimensional convolutional layer of a neural network to generate intermediate digital data, where L is a positive integer greater than or equal to 2, and where the neural network includes a plurality of additional layers; and processing the intermediate digital data using the plurality of additional layers to generate information about the target.

Parametric CNN for radar processing

A wireless multimode system includes: an array of N antenna elements that includes a first portion of M antenna elements and a second portion of L antenna elements; M transmission amplifiers configured to transmit, via the M antenna elements, frames of transmit data, where the frames of transmit data include transmit radar signals and transmit communication signals; M reception amplifiers configured to receive, via the M antenna elements, frames of receive data, where the frames of receive data includes receive communication signals; and L reception amplifiers configured to receive, via the L antenna elements, receive radar signals; and a resource scheduler configured to allocate bandwidth for transmit radar signals and transmit communication signals within the frames of transmit data based on one or more predetermined parameters.
