RF interference suppression method based on sea-clutter-wave maintaining for HF Ground-wave radar;

Ecological role of weeds conserved in orchard in red soil hilly area during hot-dry season;

So we give a brief analysis of three types of circuit techniques for realizing low noise and offset, bring up with a chopper-hold structure suitable for bio-medical processing.

Analysis of sea clutter distribution based on wavelet transform;

The method to detect signal on the sea with strong sea clutter;

Review of modeling of sea clutter and target detection based on statistical models;

It not only can simulate the sea clutter in different sea states,but also can make dynamic simulation to island and coast-line in different courses and navigational speeds of ship.

Therefore,serious sea clutter interference occurs through antenna beam and range sidelobe accompanied with pulse-compression when observing precipitation adjacent to the sea surface.
