摘要: 为了适应对高精度扩频测控设备的研制需求,研究了高动态直扩信号模拟器中相位模拟技术,提出了一种基于在线校正和线性内插相结合的相位模拟方法,避免了以牺牲实现资源来提高相位精度的模拟方式,可高精度地模拟出高动态情况下接收机与目标方之间的相对运动。理论分析、仿真结果、实测数据均验证了方法的有效性,已成功应用于某航天型号模拟器产品中。

Abstract: To meet the development requirements of high-precision spread-spectrum telemetry track and command (TT&C) equipment, the high-precision simulation technology of direct sequence spread spectrum (DSSS) signal is studied and the simulation technology of carrier phase is proposed based on online correction technology and linear interpolation, which avoids the simulation of improving phase precision by sacrificing resources and can simulate relative motion between a receiver and an object. The effectiveness of this algorithm has been corroborated with theoretical analysis, simulation and measured data and has been applied to certain spaceflight simulator successfully.

Key words: high dynamic, direct sequence spread spectrum signal, simulator, correction technology online, linear interpolation, phase simulation
