Abstract

The pulse patterns constructed with existing methods don’t perform well in hit property or in pattern number. Aimed at this problem, a new method to construct pulse patterns for multiple time-hopping (TH) pulsed pseudolites (PLs) is proposed. In the proposed method, first different groups of congruence codes are generated; next with the generated congruence codes, different TH slot index (THSI) base matrices are built; then according to the effective data to pseudorandom noise (PRN) code duration ratio of the PL signal, by means of selecting several different THSI base matrices and horizontally concatenating them into one, different THSI tables are formed; finally by way of concatenating each row of a formed THSI table into a sequence and further mapping each entry of the sequence into binary codes, different pulse patterns for different PLs are constructed. The final simulations show that compared with other similar pulse pattern construction methods, the proposed method can give better overall performance in hit property and pattern number, and this will bring more benefits for PL applications.

利用生成的同位码构建跳时伪基站的脉冲模式

用现有方法构建的脉冲模式在命中率和模式数方面表现不佳。针对这一问题，我们提出了一种为多跳时脉冲伪基站（PL）构建脉冲模式的新方法。在所提出的方法中，首先生成不同的同位编码组；然后用生成的同位编码建立不同的 TH 槽指数（THSI）基矩阵；接着根据 PL 信号的有效数据与伪随机噪声（PRN）码持续时间比，通过选择几个不同的 THSI 基矩阵并将它们水平串联成一个，形成不同的 THSI 表；最后，将所形成的 THSI 表中的每一行连接成序列，并进一步将序列中的每个条目映射为二进制编码，从而为不同的 PL 构建不同的脉冲模式。最终的仿真结果表明，与其他类似的脉冲模式构建方法相比，所提出的方法在命中属性和模式数方面具有更好的综合性能，这将为 PL 应用带来更多益处。
