Since UWB technology has a lot of advantages such as high date rate, low power spectral density, high precision location identification and inherently exceptional multipath immunity, it has become the research focus in the wireless communication field.In the research work of this paper, An UWB receiver signal acquisition system for the purpose of object recognition is designed through time-interleaving of multiple ADC sample way.In this paper, the basic theory of UWB communication and the facts which affect the high speed ADC SNR are introduced at first. And then, the whole design procedure of the entire system was described in detail according to the system request and the high speed ADC characteristic, including comparison of schemes, selection of key chips, hardware designing, FPGA software designing and the PCB designing at last.While introduced the PCB design, the high-speed circuit characteristics and problems brought from them are theoretically analyzed. Then the design method of the high speed acquisition system, including modeling and simulation application are given as well, so as to ensuring the signal integrity and EMC.
