Ranging performance of single-frequency MPPSK integrated system

The dual-frequency MPPSK-MODEM platform is a flexible one. When ranging accuracy request is low or platform is particularly affected by power limitations, the platform would perform both data transmission and range measurement with single frequency modes. In this paper, the ranging resolution of MPPSK pulse waveforms with the match filter and impacting filter processing method are discussed, respectively. Also, the selection of MPPSK modulation parameters for ranging is considered. In particular, requirements that allow for employing such special parameter values for range measurements with high accuracy and high range are investigated. Moreover, high repetition frequency (HRF) bi-phase code MPPSK pulse train based on m sequence are presented, the ranging accuracy of the proposed signal with the match filter processing method is deduced. In addition to theoretical considerations, the paper presents system simulations and measurement results of single-frequency MPPSK integrated systems, demonstrating the highperformance of ranging applications.
