Abstract

As Time difference of arrival (TDOA) needs high precision data for time delay estimation, a hardware system which can sample high precision data is presented in this paper. FPGA and DSP are taken as the general architecture in the hardware design. The precision of the system is improved by using GPS to synchronize time. The structure of the hardware system and the realization of data collection design flow are introduced. Finally, an estimation of time delay result by the cross correlation method will be given. Experiment results show the hardware design is effective and feasibility.
