Bar is fixed on horizontal sliding groove, and model is located in tank water；Radar is placed in the instrument connection.
The instrument connection bottom is fixed with perpendicular positioning hammer.
The tank water is salt solution, and conductance is adjusted by adjusting sodium chloride content.
The depth of water of the tank water is more than the 4/5 of tank depth.
The model fix bar is the scalable body of rod.
The instrument connection is all higher than 1.5 of distance between instrument connection and model relative to the distance at any point in tank
Times.
The model is all higher than 1.5 times of distance between instrument connection and model relative to the distance at any point in tank.
The horizontal sliding groove level is fixed.
The beneficial effects of the present invention are：The electrical conductivity for a certain value that can be needed and the radar of absorption coefficient are propagated
Medium, preferable pitch of holes carries out all kinds of radar tests；The radar test value of the different distance of each model is can obtain, is radar
Experimental study provides real data and reliable test in hole.
