The system can realize the function switching of three kinds of information systems of radar detection, digital communication and electronic countermeasure through parameter configuration and chip configuration; through the any waveform generating module, analog signals or digital signals used for three kinds of systems can be generated; the system comprises an emitting loop and a receiving loop; the emitting loop and the receiving loop use identical light sources, so that the system coherence is ensured; meanwhile, the microwave signals are processed in the photonic filed, so that the advantages of high bandwidth and low noise performance are realized. The system can realize the functional integration of the information system; the environment adaptability and reconfigurability of the system can be improved; the system can be widely used in the information technology fields such as ultra-wide band radar, digital communication and electronic countermeasure.

Description

technical field [0001] The invention relates to the technical field of photon information processing, in particular to a radar communication countermeasure integration system based on microwave photons. Background technique [0002] With the diversified development of the application requirements of the radar system, the detection environment of the radar system tends to be complicated, the detection mode tends to be diversified, and various functions tend to be integrated. In the traditional radar design, the hardware and corresponding functions are bound, and there are great difficulties in equipment maintenance, function expansion and system upgrade, and a large number of repeated designs also cause a waste of resources. On the other hand, with the continuous improvement of the operating frequency band and bandwidth of the radar system, the traditional electronic technology has gradually approached the "electronic bottleneck" limit. As an important technology to improve ...
