Abstract

A radar system for a vehicle includes a first radar sensor and a second radar sensor, both configured to transmit and receive radar signals in the same frame. A processor system, coupled to these sensors, transmits a first set of chirps from the first radar sensor and a second set of chirps from the second radar sensor. Each chirp has specific start and end times, and frequency bands, with differing frequency ranges. The chirps from the two sensors are interleaved such that the start frequency of the second sensor's chirps lies between the start and end frequencies of the first sensor's chirps, and the end frequency of the first sensor's chirps lies between the start and end frequencies of the second sensor's chirps. Additionally, each chirp from the first sensor overlaps in time with at least a portion of the chirps from the second sensor.
