An HLS model of an automotive RADAR signal processing algorithm has been developed for the purpose of comparison between the HLS model and the existing HDL model. The connection diagram of a SE/NE 566 VCO is shown in the figure below. The type of application that are requiring an FMCW radar are listed in this slide. The Texas Instruments LMX2581 phase-locked loop (PLL) frequency synthesizer integrates a voltage-controlled oscillator (VCO) that covers from 50 to 3760 MHz and offers perhaps the best phase-noise. Variation in load magnitude and phase will change the frequency of the VCO as a function of the oscillator quality factor. A typical radar module consists of a transmitter, voltage-controlled oscillator (VCO), and receiver ICs, along with a microcontroller unit (MCU). The chosen VCO type for this project is a Negative Resistance oscillator. • Dual-band VCO is presented to generate two LO signals • Sub-sampling is used to reduce phase noise • Pulse width and charge current can be tuned to control the loop bandwidth • Dual-band PLL achieves low phase noise and power consumption performance 27. With everything but the kitchen sink built into it, the device is quite the behemoth. The radar receiver requires a limited tuning range to compensate for transmitter and local oscillator frequency changes because of variations in temperature and loading.

The FMCW voltage controlled oscillator (VCO) output is frequency multiplied to the 76 GHz-band signal by x m mul-. The VCO uses the distances and the VI between each observer location and the orienting point to determine the VA for each observer. This DC voltage is made tunable through a potentiometer connected between 5 V and ground to tune the transmit frequency.
