Abstract :
The high-frequency (HF) oceanographic radar system located at the coast is well-known as a tool for synoptic on-line mapping. Recently oceanographic radar systems have been officially recognized by the International Telecommunication Union (ITU) to have their own frequency bands. However, the assigned spectral bandwidth for radar signals is quite narrow. It leads to loosing the required range resolution. To avoid this disadvantage new high-resolution processing techniques can be applied. The signal processing sequence is considered in order to improve target range resolution by simple software modification. A test example of high-resolution technique for range processing is shown using measured signals of oceanographic HF frequency modulated continuous wave (FMCW) radar.
