V- ULTRAWIDEBAND V-FED ANTENNA FOR DEEP GROUND PENETRATING RADAR

摘要

The present invention relates to an ultra-wideband V-feeding type antenna for a high-depth surface transmission radar, and more particularly, an angle with respect to the horizontal dipole axis by folding forward (in the direction of the main beam and the underground direction in the surface transmission radar) around the power supply unit. It is composed of a V-shaped V-shaped part and the first and second horizontal dipoles folded in the outer direction at both ends of the V-shaped part and positioned parallel to the horizontal dipole axis. When receiving from the receiving side of the bistatic ground transmission radar, the deep It relates to an ultra-wideband V-feed type antenna for a high-depth ground transmission radar capable of receiving a reflected wave signal generated from a deep underground discontinuity at a larger level, and the total length of one arm of the antenna according to the antenna operation frequency and operation mode When is determined, optimize the length, angle and width of one arm of the V-shaped part, and the length and width of each of the first and second horizontal dipoles in order to improve the ultra-wideband operation of the antenna and the direct wave ratio to the underground reflected wave. There is an effect of improving the detection performance of the high-depth target of the surface transmission radar system determined by the technique.
