BPSK調(diào)制器時延校準技術(shù)研究
[Abstract]:With the rapid development of satellite technology, the role of distance measurement in satellite navigation and positioning, remote sensing and other fields is becoming more and more important. In order to ensure the accuracy of the measurement, we must first find a way to measure the absolute transmission delay of the transmitting and receiving equipment. BPSK signal modulation mode is one of the main modulation methods in navigation and positioning system, and the delay measurement of BPSK modulator is the difficulty of the time delay measurement of the whole transmitting device. The key problem of accurate measurement of transmitter delay is how to measure modulator delay accurately. In this paper, the definition of time delay in transmission system is discussed, and the characteristics of time delay are introduced, aiming at the problem of time delay measurement of BPSK digital baseband modulator used in satellite navigation and positioning system. And software demodulation BPSK digital signal measurement system delay principle process. A calibration system for testing the absolute transmission delay of BPSK modulator is integrated with a universal instrument. The characteristic of the system is that the digital oscilloscope is used as the high-speed data collector to capture the modulation signal waveform, and through the quadrature demodulation software, the time-domain correlation principle is used to measure the insertion time delay of the modulator in the BPSK state.
