A microwave standard signal generator that generates microwaves with the same frequency as the transmission pulse of a weather radar device, an amplitude modulator that receives the output of this generator as input, and a device that simulates rainfall echoes. The microwave standard signal generator is equipped with a storage circuit that stores a signal as digital data, and a D/A converter that converts the digital data into an analog signal. The microwave generated by the amplitude modulator is amplitude-modulated by the amplitude modulator, and the modulated microwave obtained from the amplitude modulator is input to the weather radar device as a calibration signal for the reflected signal strength of the weather radar. Features: Weather radar calibration device. 2. The first term in which several types of analog signals with different bandwidths obtained through a D/A modulator are stored in a storage circuit by processing the digital data of a signal simulating a rain echo through a low-pass filter. Calibration device for the weather radar described.
