Acquisition Scheme for Impulse Radio UWB TTC Signal

摘要

摘要: 脉冲超宽带测控系统作为一种航天测控新体制，可有效提高系统的隐蔽性和抗干扰性。该文针对脉冲超宽带测控信号的捕获问题，提出利用基于部分匹配滤波与快速傅里叶变换(Partial Matched Filtering and Fast Fourier Transform, PMF-FFT)的捕获方法完成对脉冲相位、伪码相位和多普勒频率的3维捕获。又针对搜索空间大、捕获时间长和多普勒频率估计精度低的问题，提出了一种改进的捕获方法。该方法采用两步捕获法对时延相位进行捕获，同时利用修正的Rife算法对多普勒频率进行进一步精细估计。仿真结果表明，该方法可有效提高捕获速度，减小捕获时间，且能显著提高多普勒频率估计精度。

Abstract: The impulse radio Ultra-WideBand (UWB) Tracking, Telemetry, and Command (TTC) system is a new kind of TTC system that can greatly improve the concealment and anti-interference performance. To solve the acquisition problem of the impulse radio UWB TTC signal, an acquisition scheme based on Partial Matched Filtering and Fast Fourier Transform (PMF-FFT) is proposed to accomplish the three-dimensional acquisition of pulse phase, pseudorandom code phase and Doppler frequency simultaneously. Then, according to the problem of excessive search space, long acquisition time and low estimation accuracy of Doppler frequency, a new improved acquisition scheme is proposed. It adopts the two-step scheme to accomplish time delay phase acquisition, and uses the modified Rife algorithm to further estimate the Doppler frequency. Simulation results show that this scheme can effectively improve the acquisition speed, reduce the acquisition time, and greatly improve the estimation accuracy of Doppler frequency.
