Introduction

This is a K-band millimeter wave radar sensor system, which adopts FMCW modulation mode with high complexity. It can detect up 3 persons' location and speed within 5 meters.

It can detect the range and speed of stationary human body and corresponding moving target, and has high ranging and velocity accuracy. The antenna with one transmitter and one receiver is adopted, and the radar transceiver link has high isolation; the RF MMIC and antenna are coplanar, which can reduce the RF link loss. Taylor algorithm is used to synthesize the antenna pattern with low sidelobe. The sidelobe suppression ratio is better than - 15dB, which makes it not easy to be interfered by ground moving targets, and can improve the detection performance of radar.
