Problems solved by technology

However, traditional desktop instruments such as oscilloscopes and spectrum analyzers cannot be used in receiver performance testing because they do not have optical fiber interfaces or digital baseband signal processing and analysis capabilities that meet the needs of radar receivers, resulting in lack of testing and verification methods.

Description

technical field [0001] The present invention relates to the field of communication. More specifically, it relates to a radar receiver digital baseband signal acquisition and analysis system and method. Background technique [0002] The receiver of the modern radar system usually adopts the optical fiber as the real-time transmission mode of the digital baseband signal. In order to evaluate the performance of the receiver effectively, it is necessary to use the digital baseband signal analysis method to complete the verification of the performance index of the receiver. However, traditional desktop instruments such as oscilloscopes, spectrum analyzers, etc., cannot be applied in receiver performance testing due to lack of optical fiber interfaces and digital baseband signal processing and analysis capabilities that meet the needs of radar receivers, resulting in lack of testing and verification methods. .
