いていた。For purposes such as increasing detection distance, removing the influence of obstacles near the ground, and operating from behind shielding objects, we have installed a foldable mount that allows radio antennas to be positioned high above the ground. There are many things prepared. These radar devices have radio antennas on mounts that are unstable during operation.
Perturbations in the radio antenna section increased due to the effects of vehicle vibration, wind, etc., leading to a decrease in pointing accuracy and reliability of the onboard electronic equipment.
