Shipborne broadband active scaler in complex electromagnetic environment and calibration method thereof

The invention provides a shipborne broadband active scaler in a complex electromagnetic environment. The shipborne broadband active scaler comprises a micro-control processor, an electro-optical modulator, a WIFI module, a broadband antenna and a corresponding radio frequency component. The scaler is used for carrying out delay simulation on a microwave signal received by the antenna, and after delay processing is completed, the delayed microwave signal is transmitted back through the transmitting antenna; the scheme can work at multiple frequency bands and has the capability of simultaneously calibrating multiple frequency bands. The invention further provides a calibration method of the broadband active scaler in the shipborne complex electromagnetic environment. According to the scheme, a plurality of optical fiber delay line methods are adopted, delay amplification and forwarding can be carried out on received radar signals, and the influence of ground clutters is overcome. 本发明提供了一种船载复杂电磁环境下宽带有源定标器，包括微控制处
