阅读说明：本技术 一种雷达系统 (Radar system ) 是由 杨晨 刘劲楠 陈佳民 刘培 于 2019-06-20 设计创作，主要内容包括：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。(A radar system is applicable to an automotive radar for automatic driving, such as an automotive millimeter wave radar; the radar sensor comprises at least one radar sensor, wherein a first radar sensor in the at least one radar sensor comprises a data merging module (402) and a plurality of radar single chips (401), wherein each radar single chip (401) comprises a first radio frequency front end (4011) and a first microprocessor (4012); the first microprocessor (4012) is used for preprocessing echo data acquired by the first radio frequency front end (4011), and after the echo data are merged and transmitted by the data merging module (402), the preprocessed echo data are post-processed by the next-level processor, so that point cloud data of the radar system are generated. Pre-processing the echo data by a first microprocessor (4012); the computational burden of a subsequent processor is reduced, the caching capacity and the data throughput capacity of the microprocessor are improved, the resource distribution is more reasonable, and therefore the adaptability of the radar system to the large-scale antenna array radar sensor is improved.)
