    Abstract:

    Aiming at the Existing problems of ultrashort wave radio that detection process cannot be detected in different places, destroy the current connection state radio, not to much radio detection at the same time, developing a quick wireless detection system, through the beidou satellite navigation system and radio test adapter device、the testing platform, make double wireless channel including the RF signal channel and Beidou satellite channel between stations and testing platform. Short message The Beidou satellite system is used to measure the distance between the stations and testing platform, calculate the attenuation of the radio frequency signal, use a certain algorithm to compensate, and through the Beidou short message to carry out the transmission and correction of the relevant information in the detection process, to achieve the detection of the station's main transmission and reception Performance indicators. By using the testing system to test the 60 km away from the radio, compared with the field measurement, the frequency error is within 10-6, transmission power, sensitivity, modulation error within 5%, within 20 minutes to complete the two different locations radio detection and meet the needs of radio index rapid detection, improve the efficiency of different radio detection.
