Ultimately, this paper conducts a study on the thunderstorm identification algorithm based on SCI algorithm, storm cell identification part of SCIT algorithm. 2 Methods This experiment mainly applies the simulated airborne weather radar reflectivity to achieve thunderstorm identification, thus realizing the ...
Recent developments in radar signal processors allow for improvement in clutter suppression. For example, one approach compensates for the effect of notching by using advanced spectral filter that interpolates over notched spectral lines. The limitation of spectral filtering techniques is the effect of ...

Such methods may be employed with coils on either side of (or both sides of) a programmed magnet. Although magnetizable material (e.g., of programmed magnet 1402) is shown in FIGS. 14A and 14B to be round, one skilled in the art will recognize that different shapes of magnetizable ...
This paper presents an algorithm of sea clutter suppression using graphics processing unit (GPU) to meet the real-time requirement in the general radar terminal system. The main idea is to convert an infinite impulse response (IIR) filter to a finite impulse response (FIR) filter, which is ...
