26 GHz 和 79 GHz UWB 频段用于汽车短程雷达应用。本文介绍了适用于两个频段的单芯片前端 IC。 26 GHz 的脉冲振荡器可以产生 UWB 短脉冲。它仅在短工作周期内消耗电力；因此，它可以实现高效节能的雷达。使用 IC 演示了由两个同步雷达组成的立体雷达。还演示了基于基带延迟的混合波束形成技术。讨论了所提出的 79 GHz UWB 脉冲雷达的脉冲前端架构，该架构有望降低功耗。还报告了一些电路元件的性能。
The 26 GHz and 79 GHz UWB frequency bands are used for short-range radar applications for automobile. In this paper, single chip front-end ICs for both frequency bands are presented. The pulsed oscillator at 26 GHz can produce UWB short pulses. It consumes power only during short duty cycles; thus, it allows a power-efficient radar. A stereo radar, which comprises two synchronized radars, is demonstrated with the ICs. Hybrid beam forming techniques based on base-band delay are also demonstrated. The pulsed front-end architecture of the proposed 79 GHz UWB pulse radar is discussed, which is expected to reduce power consumption. The performance of some circuit elements is also reported.
