analog element meaning in Chinese

模拟元件

Presents the development of modern signal processing techniques , a new implementation method which realizes quadrature coherent detection by direct sampling of if signal generated during the implementation of traditional quadrature coherent detection with analog elements in the form of two parallel baseband channels where in phase ( i ) and quadrature ( q ) components of ceived if singnal where , the imperfect matching of the separate channels due to the analog elements results in high phase and amplitude which meets the needs for high performance radar signal processing , the elementary principles and the implementation process for each method and concludes from simulation results to compare their features and application conditions that the new approach can satisfy of the requirements of high performance sp
针对近年来提出的通过直接中频采样来实现正交相干检波的方法，分析了其基本实现原理，并用统一的观点解释了迄今为止国内外基于此提出的各种实现方法；对每一实现方法的基本原理和实现过程都作了分析，并给出了计算机仿真结果；在此基础上比较了各方法的性能指标及适应条件.理论分析和仿真结果证明，这一方法完全可以满足高性能信号处理的要求
