Abstract: The techniques of this disclosure relate to object range and velocity detections from varying radar pulse repetition times. A device includes a transmitter, a receiver, and a processor. The transmitter is configured to transmit a series of electromagnetic pulses within a frame having a varying pulse repetition time between electromagnetic pulses. A center frequency of the electromagnetic pulses varies by a frequency step. The receiver is configured to receive a series of corresponding reflected electromagnetic pulses reflected from an object. The processor is configured to determine range and velocity information of the object based on the received series of corresponding reflected electromagnetic pulses. By varying the pulse repetition times between consecutive pulses in a radar frame, the radar system may improve a range resolution, particularly in the case of frequency-modulated continuous-wave (FMCW) radar systems.

Abstract: This document describes techniques and systems of a radar system with modified orthogonal linear antenna subarrays and an angle-finding module. The described radar system includes a first one-dimensional (1D) (e.g., linear) subarray; a second 1D subarray positioned orthogonal to the first 1D subarray; and a two-dimensional (2D) subarray. Using electromagnetic energy received by the first 1D subarray and the second 2D subarray, azimuth angles and elevation angles associated with one or more objects can be determined. The radar system associates, using electromagnetic energy received by the 2D subarray, pairs of an azimuth angle and an elevation angle to the respective objects. In this way, the described systems and techniques can reduce the number of antenna elements while maintaining the angular resolution of a rectangular 2D array with similar aperture sizing.

Abstract: This document describes techniques and systems directed at slow-time modulation for multiple radar channels. A set of transmit channels are modulated using code sequences to phase-modulate transmission signals. A second set of transmit channels are modulated using the same codes for phase modulation as well as using a frequency phase shift. Demodulation is achieved by multiplying received signals by the code sequences. Fast Fourier transforms (FFT) are applied to the received signals to generate a range-Doppler map for each receive channel. A non-coherent integration is performed on the range-Doppler maps to form a range-Doppler average map. The range-Doppler average map is shifted by the frequency phase shift, and the minimal of the range-Doppler average map and the shifted range-Doppler average map is retained. These techniques may reduce the impact of signal residue and increase angular resolution by enabling multiple transmit channels to be utilized.
