Near-Field to Far-Field Transformation Including the Effect of Ground Bounce
نویسندگان
چکیده
The far-field Radar Cross Section (RCS) measurement of the actual target requires a long measurement range, which can be realized in the outdoor site. One of the problems in outdoor measurement is the difficulty to avoid the effect of ground bounce. Some sites overcome the difficulty by the exploitation of the ground bounce in RCS measurement [1][2]. Meanwhile the RCS measurement of the large actual target in the far-field region is very difficult. The application of near-field to far-field RCS transformation method [3]-[5] is desired. However the non-uniformity of the illuminated electric field on the target causes some errors in the far-field RCS prediction. We propose a novel near-field to far-field RCS transformation method that is suitable for an outdoor RCS measurement. The validity of the proposed method is investigated by the simulation and measurement results.

Seismic Behavior of Jacket Offshore Platform Subjected to Near and Far Field Ground Motions
Offshore structures such as jacket platforms have to inevitably be designed against sever environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...

The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure. For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered. Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...
متن کاملEffects of Far- and Near-Field Multiple Earthquakes on the RC SDOF Fragility Curves Using Different First Shock Scaling Methods
Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...
متن کاملA Strong Ground Motion Catalogue of Selected Records for Shallow Crustal, Near Field Earthquakes in Iran
Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and ...
