A radar system employs a self-test to determine time synchronization of cascaded radar transceiver integrated circuits (ICs) in the radar system that are used in a motor vehicle. To effectively detect information in the environment, the radar system periodically executes the self-test operation by sending a trigger signal to at least one follower radar transceiver IC. Moreover, the leader radar transceiver IC generates a chirp signal at a set frequency and transmits this. In response to receiving the trigger signal, the at least one follower radar transceiver IC receives the chirp signal transmitted from leader and generates its own local chirp signal with the set frequency, but also includes a frequency offset. The local chirp signal is then used to down-convert the received signal into an intermediate frequency (IF) signal. The IF signal is filtered, analog-to-digital converted, and processed to determine a beat frequency. The beat frequency is compared to the frequency offset to determine the level of synchronization between the leader radar transceiver IC and the at least one follower radar transceiver IC.

To control the rate of a mechanical watch with high precision. [Solution] In mechanical watches, A sensor detects the vibrations of the balance, and the cumulative frequency is compared with the clock cumulative frequency of the reference oscillator to calculate the rate error. Based on this error, a control method is determined, and mechanical energy is injected into the balance by an actuator to control the rate. For even more precise control, abnormal vibrations are recorded to evaluate the reliability of the measurements and adjust the control strategy accordingly. In addition, if sensor detection is difficult, it is supplemented by phantom counts estimated from the reference oscillator. If necessary, it is also possible to identify external factors using auxiliary sensors. When high reliability is required, sensors with different detection principles can be duplicated and cross-verified. This configuration enables implementation at various levels, from basic rate control to advanced adaptive control.
