Description

technical field [0001] The invention belongs to the technical field of communication signal reception, and in particular relates to a large-bandwidth communication signal reception and analysis device and method based on dual-channel phase superposition. Background technique [0002] Signal analysis is widely used in modern communication. With the development of modern communication technology, the analysis bandwidth of signal spectrum analysis is getting higher and higher. The traditional spectrum analyzer mostly adopts the sweeping method, which uses the principle of sweeping superheterodyne reception. The local oscillator sweeps the frequency in the frequency band and the receiver is narrowband. This method is only suitable for the spectrum measurement of continuous signals and periodic signals. It is difficult to meet the challenges of measuring communication signals with frequency hopping characteristics. [0003] To detect the signal in the frequency domain, it is nec...
