Implementation of Pulse Radar Waveform Based on Software Radio Platform
School of Electronic Science and Engineering, National University of Defense Technology, Changsha, Hunan, China
Based on the frequency and phase modulated signal, the authors design some commonly-used pulse radar baseband waveform, such as linear frequency modulated waveform, nonlinear frequency modulated waveform, Costas waveform, Barker coding waveform and multi-phase coded waveform, and the authors compare their performance, such as the peak side lobe ratio, the Rayleigh resolution in time and distance resolution. Then, based on the software radio platform NI PXIe-5644R, the authors design the timing control procedures and waveform launch procedures, and make the sampling rate, center frequency, pulse period and signal power flexible and controllable. After that, the authors test and verify the various waveforms.
Key words: signal modulation / radar baseband waveform / software radio / timing control
