| 摘 要： | 遥测天线校准通常采用误码仪产生的信号经调制后送入校准天线发射，接收机收到信号解调后，再送入误码仪测量链路误码率完成单天线校准。该校准方式无法进行多天线集中校准，针对该校准方式的弊端挺出了一种多天线集中校准的方法，利用反馈式移位寄存器理论在FPGA中产生伪随机序列，给出了伪随机序列的仿真波形，并利用IN—SNEC公司接收机测试软件完成多天线集中校准源的测试。

| Abstract: | Telemetry antenna calibration commonly uses the modulated signal generated by bit error rate tester （BERT） and then the signal is sent into calibration antenna. The receiver receives and demodulates the signal, and then sends the signal into BERT to complete single antenna calibration through link error rate test. This calibration can not be used in multiple te- lemetry antenna centralized calibration. In this paper, a way of multiple telemetry antenna centralized calibration is proposed to overcome the drawbacks of this calibration. Pseudo-random sequence and its emulator waves are generated in FPGA by using the feedback shift register theory. The tests of multiple telemetry antenna centralized calibratian source are completed by using the receiver test software developed by IN-SNEC company. |
