该论文提出了一种W波段收发器阵列，采用2.4GHz本振同步技术，解决了多芯片级联毫米波雷达中信号分布成本高、阵列规模受限的问题，实现了全可扩展性，从而缩小CMOS雷达与光学成像系统之间的角分辨率差距。
Closing the angular resolution gap between CMOS radar and optical imaging systems can enable an entirely new cost-effective radar-centric perception solution, but requires extremely large transceiver (TRX) arrays to achieve LiDAR-like angular resolution. Multichip cascading of mm-wave radars [1-3] has become the norm to enable these large TRX arrays, but the size of these arrays is still limited due to challenges in achieving lowcost signal distribution across a large aperture. Today, multi-chip radar cascading solutions use mm-wave LO frequencies (20GHz [1,2], 40GHz [3]) along with on-chip frequency multipliers with modest multiplication factors (×4 [1,2], ×2 [3]). However, operating at these frequencies is cost-prohibitive and severely limits the size of the array
