Data acquisition system of adaptive wideband and narrowband radar signal

设计了一种自适应宽窄带雷达信号的数据采集系统,可根据配置的基本雷达参数自适应地实时采集4 GHz带宽下的任意宽带基带信号以及窄带中频信号,并同时将窄带中频信号转至基带,便于后续的信号处理。给出了该自适应数据采集模块的具体硬件实现,并对该系统的具体功能和性能指标进行了测试,验证了该方案的正确性。

A data acquisition system of adaptive wideband and narrowband radar signal is designed. It can acquire any wideband baseband signal and narrowband IF signal in real time adaptively according to the configured basic radar parameters and transfer the narrowband IF signal to baseband at the same time so as to facilitate the subsequent signal processing. The hardware implementation of the adaptive data acquisition module is presented, and the specific functions and performance indexes of the system are tested to verify the correctness of the scheme.
