System, to set the signal amplitude in tlv triple and phase characteristic, target echo signal by test requirements document at a certain Angle Position
On with tlv triple aerial radiation give tested target seeker.
Realize process particularly as follows:
The angle position of tlv triple radiation center one azimuth/angle of site coordinate system defines.This coordinate
The initial point of system is on the intersection point of turntable frame axis.
The motion of signal radiation center can be described by angle scintillations equation.In angle scintillations equation, radiation center phase
It is the function of following factor to the angle of reference direction:
1) Angle Position of radiation signal source；
2) relative amplitude of each signal and phase place in coordinate system origin；
We can be by each the millimeter wave antenna unit institute radiation signal in program controlled phase shifter control tlv triple
Phase place, the phase place being allowed to radiate on array co-ordinates system initial point at sphere signal is equal, three millimeter wave antenna lists of such tlv triple
The amplitude center of institute of unit radiation signal is the position of radiation center, it can be seen that radiation center position is inevitable at tlv triple area
In.
According to real use state, angle scintillations equation can be made small angle approximation, just obtain following in order to describe in radiation
The equation group of heart position:
In formula, ψ is the azimuth of radiation center,For the angle of site of radiation center, ψ 1, ψ 2, ψ 3 is three antennas of tlv triple
Azimuthal coordinate,For the angle of site coordinate of three antennas of tlv triple, E1, E2, E3 are the transmitting letter of three antennas
Number amplitude.Shown in Figure 3.
From angle scintillations equation it can be seen that amplitude E1, E2, E3 of controlling three unit just can control the synthesis of three unit
Radiation center is in the position within tlv triple, in order to position accurately, and for the ease of calculating and controlling target location, amplitude
E1, E2 and E3 control in the following fashion: i.e. three amplitude sums are constant (such as 1), then E1+E2+E3=1, so,
At turntable frame crossing point of axes, the amplitude of composite signal is just unrelated with the position of radiation center, and it is only dependent upon and is supplied to target array
The watt level of row.
Seeing Fig. 3, the benchmark defining its radiation center is the leftmost loudspeaker of tlv triple, it may be assumed that
ψ 1=0, ψ 2=ψ 3/2,
Substitute into angle scintillations equation, can obtain:
ψ '=E2 ψ 2+E3 ψ 3；
By normalized, can be reduced to:
Make ψ=ψ '/ψ 3=E2/2+E3；
Then have:
By three above formula, only it is to be understood that the azimuth of target, the angle of pitch, it is possible to calculate target in tlv triple three
The radiation amplitude of individual millimeter wave antenna, thus accurately control target emanation signal position in tlv triple.
