Specific embodiment
The present invention is a kind of discharge source location test dipole antenna linear pattern pallet, as Figure 1-Figure 4, the present invention
Including：Dipole antenna fixed part, dipole antenna support section and dipole antenna chassis portion three parts.Wherein
Dipole antenna fixed part is located at dipole antenna support section top, and dipole antenna chassis portion is located at dipole antenna
The bottom of fixed part.
Wherein, dipole antenna fixed part, as shown in figure 1, being that four reserved grooves 1 are provided with pallet 8, reserves ditch
The size of groove 1 according to used by antenna size and determine, antenna is just coincide in the reserved groove 1.Described day
Line is dipoles, and four or more than four are provided with altogether, and its quantity is consistent with the quantity of reserved groove 1.Four dipoles
Antenna is placed in reserved groove 1 according to arranged in a straight line at equal intervals, and its size of space is true by dipole antenna centre frequency used
It is fixed.For example：Center of antenna frequency is 500MHz, then antenna spacing is 0.3 meter, and pallet is long to may be set to 1.2 meters.When dipole day
After line is put into reserved groove 1, dipole antenna is covered using rubber blanket 5, the spiral shell being then made of polyphosphazene polymer vinyl chloride
Bolt is fixed, as shown in Figure 3.
In order to the test accuracy checking for combining the direction and location based on coherent signal-subspace algorithm etc. is required, it is necessary to ensure
Pallet keeps level when testing ground disposes, therefore may be equipped with horizontal checkout instrument, and horizontal checkout instrument can be placed in
On dipole antenna chassis, dipole antenna chassis bottom is furnished with adjustable bolt, and dipole can be adjusted by regulating bolt
The level on antenna chassis.The pallet 8 is designed for linear pattern, and the top of pallet 8 and dipole antenna fixed part are square
Design, is also designed to rectangle, rhombus, circle, ellipse, triangle and abnormity etc..
