| Abstract: |
| OSMAR2000(Ocean State Measuring and Analyzing Radar,manufactured in 2000) system used to extract sea surface state is a broad-beam radar,uhich is based on a frequency modulated interrupted continuouswave(FMICW) type waveform.This waveform used as a pulse compression technique combines good range resolution and high maximum range with a relatively high duty cycle.Considering other corresponding restricts, the implementation of the FMICW waveform in a practical real time radar system design process is reported in detail. The system waveform parameters designed is robust to the range and Doppler frequency aliasing. |
