The processor associates the null with the ground (e.g., steers the null toward ground or processes data so that the null corresponds to ground) to obtain a null to alleviate ground clutter when sensing weather. The null can be a single null or multiple nulls associated with different ...
函数“clutter_rcs.m”实现式(6.22);如第6.6节的清单6.1所示。它还生成了杂波RCS和CNR相对于雷达倾斜距离的图。其输出包括以dBsm为单位的杂波RCS和以dB为单位的CNR。语法如下: [sigmaC,CNR] = clutter_rcs(sigma0, thetaE, thetaA, SL, range, hr, ht, pt, f0, b, t0, f, l, ant_id) 其中 为...
The peak at 100 m is the direct path return from the ground right below the radar. Notice that the power is decreasing as the range increases, which is due to the signal propagation loss. After MTI filtering, most clutter returns are removed except for the direct path peak. The noise...
This paper presents the results of a study designed to classify weather radar clutter echoes obtained from ground-based dual-polarization weather radar systems. The clutter signals are due to ground clutter, sea clutter, and anomalous propagation echoes, which represent sources of error in quantitative...
The adaptive algorithm for choosing threshold that allow the processing to adjust automatically to environmental conditions. Experiments for the real radar signal show that the method presented can suppress the ground clutter from the radar signal effectively. 展开 关键词: ground clutter wind profiler ...
Ground clutter simulation of bistatic radar is complex due to the variety of geometry configuration.The method of clutter scatterer division in monostatic radar can be applied to bistatic radar,while it is inconvenient for clutter analysis in specific range gates.One clutter simulation approach in rang...

Current researches show that the clutter rank is much lower than the system degrees of freedom (DoFs) in the airborne MIMO radar with orthogonal waveforms. According to this conclusion, we propose the ground clutter canceller based on the clutter recovery (CCCR) to suppress the clutter and reduce...
Thus, a new technique for the simulation of ground-clutter echo is developed that better predicts the experimentally observed CPA. Experimental data from the Denver Next Generation Weather Radar (NEXRAD) at the Denver, Colorado, Front Range Airport (KFTG), and NCAR€s S-band dual-polarization ...
