Radar often operate in severe weather conditions with large temperature variations. This paper presents return loss measurements and post-processing for the evaluation of temperature sensitivity of a resistively loaded radar antenna. The antenna is placed in a drying oven for controlling the temperature. A calibration technique based on an amplitude demodulation is presented in order to withdraw the...
In this paper a first time right 24 GHz FMCW radar transceiver is presented. The MMIC has a low power consumption of 86 mW and an output power of −10 dBm. Due to the integrated IF amplifier, the conversion gain of the receiver is 51 dB and the base band signals are directly processed with an ADC. The developed antenna is a PCB dipole array with 10 dBi gain. Together with a commercial microcontroller...
