Cuda Implementation in the Em Scattering of a Three-Layer Canopy

Abstract

Abstract-Calculation of the EM scattered fields from a three-layer canopy faces intensive computational burden, when the area becomes large and obviously lames the application of the traditional serial algorithm. With the development of graphics hardware, the Graphics Processing Unit (GPU) can be used to calculate the electromagnetic (EM) scattering problems parallelly. In this paper, the Compute Unified Device Architecture (CUDA) is combined with the four-path method and the reciprocity theorem to improve the speed of calculating the EM scattering properties from a three layer-canopy which are simulated by employing the Monte-Carlo method. We get a highest speedup of 294 times in comparison with the original serial algorithm on a Core (TM) i5 CPU with a GTS460 GPU as a coprocessor.

Electromagnetic Scattering of Rough Ground Surface Covered by Multilayers Vegetation

“…The multipath scattering model has been widely applied for the calculation of electromagnetic scattering from ground covered with vegetation and obtains accordance with the measurement data [23]. Thus, the presented composite scattering model is also compared with the multipath scattering model.…”

Effect of Threshold Value on the Performance of Natural Frequency-Based Radar Target Recognition

“…The radar cross section (RCS) [52][53][54][55][56][57][58][59] of radar target can be estimated from the strength of the signal reflected from the target. The reflected signal of the radar target can be simulated using scattering analysis of the radar target [60][61][62][63][64][65][66][67][68][69]. In addition to radar detection and tracking, there have been many studies on radar target recognition [70][71][72][73][74][75][76][77][78][79][80][159][160][161][162][163][164][165][166].…”

Performance Analysis of Radar Target Recognition Using Natural Frequency: Frequency Domain Approach

“…However, there parameters give only a rough estimate of the general category of the actual target type. The reflected signal of the radar target can be simulated using scattering analysis of the radar target [36][37][38][39][40][41][42][43][44][45][46][47][48][49]. In addition to radar detection and tracking, there have been mamy studies on radar target recognition [3,7,[50][51][52][53][54][55][56][57][58][59][61][62][63][64][65][66][67][68][69][70].…”
