WebJan 9, 2024 · The algorithms consist of range-FFT, Doppler-FFT, DBF (Digital Beam Forming), and thresholding functions. In each channel, 2D FFT processing is conducted … FMCW radars estimate the target range using the beat frequency embedded in the dechirped signal. The maximum beat frequency the radar needs to detect is the sum of the beat frequency corresponding to the maximum range and the maximum Doppler frequency. Hence, the sample rate only needs to be twice … See more Consider an automotive long range radar (LRR) used for adaptive cruise control (ACC). This kind of radar usually occupies the band around 77 … See more The target of an ACC radar is usually a car in front of it. This example assumes the target car is moving 50 m ahead of the car with the radar, at a … See more As briefly mentioned in earlier sections, an FMCW radar measures the range by examining the beat frequency in the dechirped signal. To extract this frequency, a dechirp operation is performed by mixing … See more The rest of the radar system includes the transmitter, the receiver, and the antenna. This example uses the parameters presented in . Note that this example models only main components and omits the effect from other … See more
