Webcommon problem in FMCW radar where the signal source is a voltage-controlled oscilla-tor (VCO), and does not have a linear voltage to frequency characteristic. If left uncor-rected, defocusing in Synthetic Aperture Radar (SAR) images becomes worse, especially at large squint angles and wide bandwidths. Webcombine a Voltage Controlled Oscillator (VCO) with a PLL have been available in the market. The VCO is used to generate the RF, and the PLL is used to stabilize and control the frequency. The advantage of PLL-VCO in FMCW radar system is the possibility to generate the LFM signal directly at RF frequency. This flu on college campuses https://2inventiveproductions.com
