摘要
Abstract
The particularity of using DS/FH for TT&C is pointed out. Hybrid spread spectrum of TT&C acquisition project is proposed when aiming at the particularity, two of which are ameliorated in the project. The Kaiser window PMF-FFT algorithm is used to ameliorate sector attenuation and the parabola interpolation algorithm is used to ameliorate barrier phenomena. From the academic analysis and simulation , in the same integral time, the Kaiser window PMF-FFT arithmetic could reduce the peak vale attenuation and diminish the spectrum leak compared with the PMF-FFT arithmetic. The parabola arithmetic could reduce the spectrum estimation error effective and in favor of establishing later tracking.关键词
