Flight test ground measurement system for precise analysis of PCM data

摘要

The present invention relates to a flight test ground measurement system for precise analysis of PCM data, a tracking antenna for receiving an RF signal transmitted from an onboard measurement system mounted on an aircraft, and a PCM (Pulse Code) by receiving an RF signal from the tracking antenna Modulation) a receiver that outputs a data raw signal, a data processor that receives a PCM raw signal from the receiver, decodes the PCM signal, extracts and outputs a parameter that needs to be monitored in real time from the decoded PCM signal, and is processed by the data processor A PCM data recorder for storing PCM data, a data post-processor for displaying the data stored in the PCM data recorder on an operator screen, an IF data storage device for storing a PCM raw signal processed and output by the receiver, and the IF data storage device and a PCM decoder that decodes the PCM raw signal stored in the , converts it into a form that can be analyzed by the data post-processor, and outputs the decoded PCM signal. According to the present invention, it is possible to provide a flight test ground measurement system capable of receiving and storing PCM raw signals and performing precise analysis when necessary.
