Background technique
Traditional automatically controlled phased-array radar feeds processing system, cable control wire ruler frequently with cable control wire composition signal Very little big, weight weight, loss is high and instant bandwidth is relatively narrow, simultaneously because signal feeding processing system has used a large amount of electronics member devices Part makes it easy to by electromagnetic interference.Conventional waveguide and the cost of coaxial feed network are very high simultaneously, the shadow by frequency dispersion It rings.
In view of the above drawbacks, creator of the present invention obtains the present invention by prolonged research and practice finally.
Summary of the invention
To solve above-mentioned technological deficiency, the technical solution adopted by the present invention is, provides a kind of multiple wavelength optical signal delay Handle network, including solution wavelength division multiplexer, adjustable attenuator and wavelength division multiplexer;The solution wavelength division multiplexer includes several outputs Port, the wavelength division multiplexer include that several input ports, the output port and the output port are a pair of by optical fiber one It should connect to form several signal paths, the signal path is provided with the adjustable attenuator;With different wave length optical signal Signal source input the solution wavelength division multiplexer and through wavelength division multiplexer multiplex output.
Preferably, the signal path between the solution wavelength division multiplexer and the wavelength division multiplexer and the light after demultiplex Signal wavelength corresponds.
Preferably, each signal path length is different.
Compared with the prior art the beneficial effects of the present invention are: 1, multiple wavelength optical signal delay process net of the present invention The transmission signal for controlling battle array radar is modulated on light carrier by network by microwave signal, is taken full advantage of optical fiber and is transmitted small in size, transmission Small and electron-irradiation resisting advantage is lost;True time delay (TTD) technology based on microwave photon is used simultaneously, greatly improves signal Instant bandwidth;2, the present invention is different to realize by design each signal path length of wave by the way of length delay Delay interval has the advantages that fiber lengths are short, system bulk is small and integrated level is high.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of multiple wavelength optical signal delay process network of the present invention.
Digital representation in figure:
1- solves wavelength division multiplexer;2- adjustable attenuator;3- wavelength division multiplexer.
Specific embodiment
Below in conjunction with attached drawing, the forgoing and additional technical features and advantages are described in more detail.
Embodiment one
As shown in FIG. 1, FIG. 1 is the connection schematic diagrams of multiple wavelength optical signal delay process network of the present invention;It is of the present invention Multiple wavelength optical signal delay process network includes solution wavelength division multiplexer 1, adjustable attenuator 2 and wavelength division multiplexer 3.
The solution wavelength division multiplexer 1 includes several output ports, and the wavelength division multiplexer 3 includes several input ports, institute It states output port and the output port connects one to one to form several signal paths by optical fiber, the signal path is all provided with It is equipped with the adjustable attenuator 2.The adjustable attenuator 2 is used to adjust the intensity of optical signal in each signal path.
Signal source with different wave length optical signal inputs the solution wavelength division multiplexer 1, passes through the solution wavelength division multiplexer 1 It is divided into the optical signal of several different wave lengths and is exported by the output port, the optical signal is through the different signal paths It is transmitted to the wavelength division multiplexer 3 and carries out multiplex, realize multiple wavelength optical signal delay process.
The optical signal after the signal path and demultiplex between the solution wavelength division multiplexer 1 and the wavelength division multiplexer 3 Wavelength corresponds.
Each signal path length is different from each other, to guarantee that amount of delay is mutually different between each road signal.
Multiple wavelength optical signal delay process network of the present invention is modulated the transmission signal for controlling battle array radar by microwave signal Onto light carrier, takes full advantage of optical fiber and transmit that small in size, transmission loss is small and the advantage of electron-irradiation resisting;It uses and is based on simultaneously True time delay (TTD) technology of microwave photon, greatly improves the instant bandwidth of signal.The present invention is led to by the way of length delay Cross design wave each signal path length and realize different delay intervals, have that fiber lengths are short, system bulk is small and The high advantage of integrated level.
Specifically, inputting the signal source for solving wavelength division multiplexer 1 includes the n different wave that wavelength is λ 1 to λ n such as Fig. 1 Long optical signal, is divided into the road n and enters the different signal paths behind the end COM by the solution wavelength division multiplexer 1 and passed Defeated, signal path carrier wave described in each road carries out multiplex again by the wavelength division multiplexer 3 after the adjustable attenuator 2, Realize multiple wavelength optical signal delay process.
Since the transmission loss of optical fiber is small, the long distance transmission of signal is can be achieved in the present invention.
Different delayed time amount may be implemented in passage length by designing wavelength division multiplexer 3.
Since the multiple wavelength optical signal delay process network mainly uses optical fiber as the carrier of transmission signal, tool There are good anti-electromagnetic-radiation ability and stability.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive 's.Those skilled in the art understand that in the spirit and scope defined by the claims in the present invention many changes can be carried out to it, It modifies or even equivalent, but falls in protection scope of the present invention.
