Sitting to watch clouds rise. During the long and slow-moving era of automotive 3D millimeter-wave radar (1974-2020), core technology centered on transceiver devices (MMIC chips). From 1T2R to 3T4R transceiver devices, it took over a decade. Around 2020, starting with cascaded MMIC chips, 4D imaging radar emerged, and radar signals could begin to be trained by AI. By 2025, single MMIC chips had evolved from 3T4R/4T4R to 8T8R, which shifted the core technology of automotive radar: from transceiver devices to radar signals. Restoring and reconstructing the physical world from electromagnetic field information, i.e., radar imaging, has become the core technology of
