摘要

Millimeter-wave (MMW) radar systems are used in a wide range of applications today. In this paper, we present the implementation of a frequency modulated continuous wave (FMCW) radar sensor based on the off-self Infineon MMIC chip sets. This radar sensor is bistatic with one transmitter and two receivers operating at 24GHz with 200MHz of bandwidth. The design is aimed at short-range driver assist applications such as blind spot detection. Three printed-circuit-board patch antennas with l4dBi of gain and ± 50 of beamwidth are used to render a detection distance over 100 meters, and thus is suitable for short-range safety and security usages. A digital spectrum analyzer implemented using FFT with modern digital signal processors is used for both range and velocity measurement. An improved algorithm for multi-target detection using the voting concept of Hough transform is proposed. This approach recovers the range-velocity space representations of multiple moving targets from the received beat signals without involving any pairing process, which is a problematic issue and usually brings ghost targets in FMCW radars. Some field tests and simulations validating the performance of this radar sensor are also presented.
