The embodiment of the present invention discloses a radar micro-variation test tool and its control method. The radar micro-variation test tool includes: a host computer, a controller, a driver, a drive motor, a linear guide rail and a corner reflector; the host computer and The controller is connected in communication; the controller is electrically connected to the driver; the driver is electrically connected to the drive motor, and the driver is used to convert the pulse signal into an angular displacement; the corner reflector is fixed On the slider of the linear guide rail, when the driving motor rotates, the driving motor drives the corner reflector to move a corresponding displacement. In the above technical solution, a motor is added to control the linear guide rail, and the controller sends a control command to the driver, and the driver controls the rotation of the motor, so as to realize the requirement of high-precision movement of the corner reflector. In addition, a wireless module is added to the upper computer and the controller, which can carry out long-distance data transmission, so as to realize the purpose of remote control of the corner reflector.
Description
technical field [0001] The invention relates to the technical field of radar testing, in particular to a radar micro-variation testing tool and a control method thereof. Background technique [0002] Radar is an electronic device that uses electromagnetic waves to detect targets. The radar emits electromagnetic waves to irradiate the target and receives its echoes, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. In order to ensure that radar equipment is always in good working condition, radar performance parameters need to be tested at various stages of the radar equipment life cycle. [0003] The radar reflector, also known as the corner reflector, is an auxiliary device commonly used in radar testing. Since the RCS (Radar Cross Section) of the corner reflector is higher than the surrounding objects, when the radar electromagnetic wave hits the co...
