First, the method for adjustment of the synchronic dual-frequency system transmission power of this monomer provided in an embodiment of the present invention, described The synchronic dual-frequency system of monomer in, two-way source signal is correspondingly arranged on a local oscillation signal respectively；Synchronic double frequency letter to be sent Number include the first source signal and the second source signal；Double frequency local oscillator letter is obtained after first local oscillation signal and the second local oscillation signal combining Number；Synchronic two-frequency signal and double frequency local oscillation signal to be sent obtains mixed frequency signal through mixing；After the emitted link of mixed frequency signal Acquisition transmitting signal is launched after end Gain tuning device carries out Gain tuning.
Specifically, transmitting link is as shown in Figure 1 used by inventive embodiments.Two local oscillators launched in link produce two Road local oscillation signal, the first local oscillator 101 launched in link produce the first local oscillation signal, and the second local oscillator 102 launched in link is produced Raw second local oscillation signal, the first local oscillation signal and the first local oscillation signal amplify via the first variable gain in transmitting link respectively After the second variable gain amplifier 104 adjustment power in device 103 and transmitting link, the combiner 112 into transmitting link It is combined, obtains double frequency local oscillation signal.To be sent synchronic pair exported by the digital intermediate frequency transmitter 105 in transmitting link The frequency mixer 106 that frequency signal is inputted in transmitting link with double frequency local oscillation signal is mixed, and obtains mixed frequency signal.Mixed frequency signal passes through Cross the first wave filter 107 in transmitting link, the amplifier 108 in transmitting link, the attenuator 109 in transmitting link, transmitting The second wave filter 111 in the 3rd variable gain amplifier 110 and transmitting link in link, completes Gain tuning, is sent out Signal is penetrated to be launched.
Shown in Fig. 2 is to launch the flow diagram that link carries out the adjustment of transmission power according to Fig. 1, transmission power Adjustment process include：
S101：According to mission need, determine the first source signal and the second source signal by the final defeated of whole transmitting link Go out power P 1 and P2 and its difference power Δ；
Here mainly basis finally needs to send out the signal of how much power, and the first source signal and the second source signal are most Whole output power P1 and P2 is equal to the power of final transmitting signal.
S102：According to the first source signal and the final output power P 1 of the second source signal and the relative size of P2, default Multiple transmission power relation tables in, select corresponding transmission power relation table；Be stored with each transmission power relation table through The output power of two-way source signal is poor after mixing, and each output power difference in requisition for two-way local oscillation signal power and The output power of the corresponding source signal of two-way after mixed.
Multiple transmission power relation tables include two transmission power relation tables in the embodiment of the present invention, one of them is to be directed to First source signal output power is more than the situation of the second source signal output power, the other is being directed to the first source signal output power Less than the situation of the second source signal output power.In this step, according to the first source signal and the final output work(of the second source signal The relative size of rate P1 and P2, it may be determined that one of transmission power relation table, because after mixing, two-way source signal Relative size relation no longer changes, and therefore, passes through the first source signal and the final output power P 1 of the second source signal and the phase of P2 Size can be known needs be more than another way source signal output power for which road source signal output power.
S103：Using the difference power Δ as index, the transmission power relation table is searched, obtains corresponding two-way local oscillation signal The power LO1 and LO2 and mixing the output power OUT1 and OUT2 of two-way source signal needed.
In the transmission power relation table that step S102 is determined, each difference power has corresponding two-way local oscillation signal power With the output power of two-way source signal, so as to find the power LO1 that the corresponding two-way local oscillation signal of the difference power Δ needs With LO2 and mixing the output power OUT1 and OUT2 of two-way source signal.
S104：The power LO1 and LO2 that the power of two-way local oscillation signal is respectively set to obtain.
With reference to Fig. 1, in practical application, two-way local oscillation signal is set, can be by adjusting first in transmitting link respectively The gain of variable gain amplifier 103 and second variable gain amplifier 104 in transmitting link is realized.
S105：It is defeated according to the mixing of the final output power P 1 and P2 of two-way source signal and the two-way source signal for acquisition of tabling look-up Go out power OUT1 and OUT2, obtain the required gain parameter of Gain tuning device.
In practical application, this step can be：Calculate final output power P 1 and P2 and the acquisition of tabling look-up of two-way source signal Two-way source signal mixing output power OUT1 and OUT2 between difference, which is determined as gain parameter.
S106：According to the gain parameter of acquisition, Gain tuning is carried out to the mixed frequency signal.
With reference to Fig. 1, in practical application, Gain tuning is carried out to mixed frequency signal, can be by adjusting the in transmitting link Three variable gain amplifiers 110 are realized.
Default two transmission power relation tables in the present embodiment, are respectively the first transmission power relation table and the second transmitting Power relation table.
Wherein, the first transmission power relation table is directed to the first source signal output power and is more than the second source signal output work Rate situation, as shown in figure 3, it can training obtains as follows in advance：
S110：First local oscillation power preset value when to set the first local oscillator signal power be default transmitting, before mixing is set The first preset value of source signal power when two-way source signal power is default transmitting；
S111：The second local oscillation signal power is adjusted so that the output power difference of two-way source signal is equal to default the after mixing One difference power test value, the first local oscillation power preset value when the second local oscillation signal power is less than transmitting, records the output work Rate is poor, and in requisition for two-way local oscillation signal power and the corresponding source signal of two-way after mixed output power；
S112：When update times are not up to the first preset times, length is adjusted as step-length using the first predetermined difference power, The first difference power test value is updated, and returns and performs step S111.
