38683 经实测数据验证表明,估计出的视角平均误差小于5°,本文方法易于实践,具有较高的工程应用价值。 Verified by measured data show that the Angle of estimate the average error is less than 5 °, the method is easy to practice, has the high value of engineering application.
38684 通过研究二进制偏移载波(binary offset carrier,BOC)自相关函数的特点,提出了一种适用于BOC任意调制阶数的无模糊捕获算法。 Through the study of binary offset carrier (binary offset carrier, bok) the characteristics of the autocorrelation function, put forward a applicable to arbitrary BOC modulation order of fuzzy capture algorithm.
38685 将BOC自相关函数进行翻转、截取、相叠加,构造出一种新的相关函数,与原自相关函数的绝对值相加后,可以完全消除副峰。 Will bok autocorrelation function to flip, interception, superposition, construct a new correlation function, and the sum of the absolute value of autocorrelation function, can completely eliminate vice peak.
