Abstract
The continuous expansion of urbanization has led to increasingly complex application scenarios for modern urbanized traffic monitoring systems. If many fine objects such as pedestrians, roadblocks and other non-motorized targets are to be distinguished, traditional single vision sensors can no longer be adapted, and a strong demand for high-resolution millimeter wave radar has been put forward. In this paper, we propose a modular 77 GHz radar system based on Texas Instruments AWR2243 radar chip, which can allow the combination of multiple modules and can achieve a longer detection range. We describe the coherent synchronization, synchronous triggering, selected antenna orientation map and the design of the whole system. Finally we show the operating performance of the whole system by some experimental measurements.
