| description | To resolve the problem of sampling speed and real-time continuous mass storage in large instantaneous bandwidth radar signal direct Intermediate Frequency (IF) sampling, a wideband radar intermediate frequency signal acquisition and real-time storage system is developed in this paper. Firstly, according to bandpass signal’s alias-free sampling theorem, the sampling frequency is determined. And then the digital quadrature demodulation, buffer and high speed real-time continuous mass storage design scheme is proposed. Based on chassis server platform, this system uses QDRII SRAM as the buffer storage, and adopts PCIe to be the data transmission channel. It is verified in a phased array radar experimental system that this system makes a good performance and gives a feasible schema for wideband radar data acquisition. |
