摘要
针对目标自主定位的环境复杂性和高速处理数据的要求,文中用VHDL语言设计了一种基于扩频通信原理的数字相关器。仿真结果显示,该数字相关器具有很高的精度和很好的可辨识性,可以在恶劣环境下降低传输过程中信噪比的要求。
To satisfy the high speed data processing requirement of automatic orientation in complex environment, based on the spread spectrum（SS） communication system, a digital correlator by VHDL is presented. The result of behavior simulation proves the high precision and excellent identifiability of this correlator; it also could reduce the requirement of s/n ratio in communication with the atrocious condition.
