Abstract

一种雷达系统，可应用于自动驾驶的车载雷达，例如车载毫米波雷达；包括至少一个雷达传感器，至少一个雷达传感器中的第一雷达传感器包括数据合并模块(402)和多个雷达单片(401)，其中，每个雷达单片(401)包括第一射频前端(4011)和第一微处理器(4012)；第一微处理器(4012)用于对第一射频前端(4011)获取的回波数据进行预处理，经过数据合并模块(402)的合并和传输后，由下一级别的处理器对预处理后的回波数据进行后处理，从而生成雷达系统的点云数据。通过第一微处理器(4012)预处理回波数据；减少了后续处理器的算力负担，提升了微处理器的缓存能力和数据吞吐能力，资源分配更合理，从而提升了雷达系统对大规模天线阵列雷达传感器的适应性。
