Millimeter-wave (mm-wave) frequency-modu- lated continuous wave (FMCW) radars are increasingly being deployed for scenario perception in various applications. It is expected that the mutual interference between such will soon become a significant problem. Therefore, to maintain reliability of radar measurements, there must be procedures place mitigate this interference. This article proposes no...

This paper describes a 94 GHz FMCW radar system for unmanned vehicles using 1 Tx and 4 RX chips designed in 65-nm CMOS process. The measured output power of the transmitter conversion gain receiver were 9.77 dBm 26 dB, respectively. simulated noise figure chip was 8 dB. Rx antennas microstrip patch with 11 dBi on Duroid substrate. chirp period sawtooth waveform 50 μs. baseband signal bandpass-f...

This study investigates crosstalk and leakage in the Software Defined Radio implementation of Frequency Modulated Continuous Wave (FMCW) radar systems. Empirical measurements power were conducted during FMCW using National Instruments Universal Peripheral (USRP) boards. Mono-static bi-static/distributed Transmitter-Receiver configurations are compared for low micro-Doppler applications. The imp...

Human body detection is very important in the research of automotive safety technology. The extraction and analysis human micro-motion based on frequency-modulated continuous wave (FMCW) radar gradually receiving attention. Aimed at modulation effect FMCW radar, a running model proposed to study characteristics. According scattering characteristics rigid bodies, analytical expression echoes est...

A method for improving the dynamic range of frequency-modulated continuous-wave (FMCW) radar systems is presented. Bright echo signals detected with FMCW radars can carry strong phase noise sidelobes, especially at W-band and higher frequencies where extremely quiet local oscillators do not exist or are practical. These sidelobes hide targets that would otherwise be detectable by radar. Owing t...
