Embodiment Construction
[0020] 1. Integrated design of navigation radar and Beidou user machine antenna.
[0021] The antenna of the Beidou user machine and the antenna of the navigation radar are integrated and installed together, so that the position coordinates of the radar antenna are consistent with the position coordinates of the Beidou receiving antenna, so as to reduce positioning errors and improve positioning accuracy;
[0022] 2. Use Beidou timing as the reference time information of the navigation radar.
[0023] Navigation radar requires precise time. For example, when the radar captures the target, it needs to stamp the target recorded by the radar with a time stamp and so on. In short, the working process of radar and Beidou is inseparable from precise time. Utilize the Beidou time information to calibrate the timer frequency (or time) of the radar, so that the time of the Beidou is consistent with the time of the radar, for the realization of the navigation, positioning, communicatio...
