该方法利用通常的线性调频RCS测量系统进行信号采集；信号处理则采用本文介绍的正交相关数字混频器。
The chirp system, which is commonly used for RCS measurement, is utilized to collect data and a method of orthogonal digital correlation mixer is suggested to process the sampled data.
通信仿真平台的任务是对调幅、调频、单边带、二进制振幅键控、二进制频移键控、二进制相移键控、正交相移键控等七种通信信号的调制和解调进行建模和计算。
The target of the communication system flat is modeling and calculating to modulation and demodulation of seven kinds of signals:AM, FM, SSB, 2ASK, 2FSK, 2PSK, 2QPSK.
