Abstract: A bi-static integrated pulse radar in the millimeter wave band based on a digitally modulated transmitter and an analog processing receiver. The front-end correlator uses a sampler to compress the sensing data, enabling a low-speed and energy efficient digital backend while delivering a high range resolution. The radar may be implemented as a system on chip (SoC) with a total power consumption of a few hundred milliwatts (mW), a surface area of less than four mm2 with less than ten percent of the total power corresponding to the analog baseband and digital back-end. The system performance indicates the measured distance from the correlator output has an RMS error of about ten centimeters (cm) and the integral non-linearity is less than ten cm across the entire target range, demonstrating the superior range resolution with superior energy efficiency.
