Abstract

The invention discloses a method for self-adaptive synthesis and health diagnosis of multi-channel wide dynamic data, which is mainly used in radar system data sampling with higher requirements on dynamic range. In order to achieve a high dynamic range and ensure sensitivity, radar system design usually uses multiple channels with different gains to sample at the same time, and then synthesize the multi-channel data into one channel. The invention ensures the high efficiency and reliability of multi-channel data synthesis through methods such as self-adaptive gain correction, inflection point identification based on intermediate frequency sampling, optimum working range and hysteresis comparison channel selection, automatic fault identification and removal, and the like.

Description

technical field [0001] The invention relates to the field of information collection and data processing of a radar signal processor, in particular to a multi-channel wide dynamic data adaptive synthesis and health diagnosis method. Background technique [0002] The sensitivity and dynamic range of the radar depend on the performance of the receiver and the ADC circuit of the signal processor. In radar design, the performance of the analog-to-digital conversion circuit ADC often cannot meet the requirements. In order to achieve a larger linear dynamic range while ensuring higher sensitivity, the design of radar receivers and signal processors often adopts the method of multi-channel sampling. After amplification, it is transmitted to the radar signal processor, which restores the multi-channel signals according to the high and low gains and then synthesizes one signal. [0003] There are many technical problems in the acquisition and data synthesis of multi-channel signals....
