Description
Technical field
The present invention is about a kind of millimeter wave frequency band seeker-fuze integration receipts that can be widely applied to communication, radar, multiple fields
Send out front end structure, be particularly well-suited to millimeter wave frequency band radar seeker and influence fuse composite integrated integrated receiving and transmitting front end design.
Background technology
In millimeter-wave systems, the performance of system is played a crucial role by receiving and transmitting front end.Millimeter wave transceiving front end passive circuit
Theoretical Design is mainly concerned with millimeter wave band bandpass filter and waveguide one microstrip transition, mainly includes amplifier, frequency mixer and opens
Close.Front ends of millimeter waves system is mainly by emitter, receiver, signal source, base band signal process machine and various interface equipment
Composition.Millimeter wave transceiving front end is integrated into a millimetre integrated circuit millimeter wave transmitter module and receiver module exactly.Do
Being a system, the elementary cell millimetric wave device of millimeter wave transceiving front end composition determines millimeter wave the most to a great extent
The quality of receiving and transmitting front end performance.Along with the development of millimetric wave device, millimeter wave transceiving front end experienced by be printed by microwave from initial
Circuit and discrete device form hybrid microwave integrated circuit (HMIC) until the most popular monolithic integrated microwave circuit,
Weight and volume reduces again and again, and power and frequency then improve constantly.Millimeter wave is wavelength electromagnetic wave between 1～10mm
Spectrum, respective frequencies scope 3GHz～30GHz.From the point of view of frequency, millimeter wave low side is connected with microwave, high-end and infrared, light
Ripple is connected, so it is collection microwave, a comprehensive subdiscipline for two subject knowledges of optics that millimeter wave is developing progressively, it is special
Point is that wave beam is narrow, maintain secrecy and antijamming capability is strong, bandwidth capacity greatly, easily realizes image, numeral compatible.Millimeter wave equipment
Requirement on machining accuracy is high, and performance impact to be minimized by the most greatly by the parasitic parameter of components and parts, and this results in millimeter
Ripple components and parts price is relatively costly.
Along with developing rapidly of aeronautical and space technology, it is desired to multiple types, on a large scale, at high speed, the trend development such as the most motor-driven,
Aircraft is made to become sufficiently complex with the intersection situation of target.In recent years, occur in that the working frequency range of radar fuze is brought up to
The trend of millimeter wave frequency band.Millimeter-wave technology and application through the development of many decades achieved with compelling breakthrough, but at present
Still it is in Growth Development period.New material, new component and transmission line continue to bring out and new manufacturing process and technology will
Millimetre integrated circuit brings up to new height.Cost is high is still to restrict the main bugbear that millimeter-wave technology is widely applied, and reduces into
This and raising reliability are the research directions that millimeter-wave technology is important.
Millimeter-wave seeker is the main direction of studying in radar guidance field, if it is possible to compound influence fuse function, will have
Effect improves targeting precision.Key component in millimeter-wave seeker framework is receiving and transmitting front end, plays non-in the entire system
The most important effect, can its performance directly affect the index of whole system and reach.Grinding both at home and abroad of millimeter wave transceiving front end
Study carefully and the most progressively develop to miniaturization, lightweight, solid state and high reliability direction.If able to it is compound in receiving and transmitting front end
Fuze detection function, just can realize drawing system one complex function；And required fringe cost is extremely low, stable performance, technology becomes
Ripe, possess the condition promoted in engineer applied.But, how to realize being applicable to the seeker-fuze integration of Millimeter Wave Pulsed system
Receiving and transmitting front end, becomes for the difficult problem urgently broken through.
At present, the research to seeker-fuze integration technology both at home and abroad, also rest on the technical scheme demonstration stage, there is not yet into
The experimental prototype of merit or Related product.These technical schemes use the discrete detection system of two sets to realize target seeker and fuse mostly
Two kinds of functions, and carry out signal fused system-level.Such two discrete detection systems of set cause cost and are significantly increased, and two are
Poor compatibility between system, causes the problems such as unstable properties.And, the reception mode of system mainly uses millimeter wave active-passive composite
Or the modes such as IR Passive reception, and combine the missile-target distance information that target seeker function provides, analyze and improve fuze function
Initiation precision and anti-interference.But under these systems, owing to parser is complicated, external environment influence factor is many, time
Territory control accuracy is the highest, and the minimum detectable range and the detection accuracy that cause fuze function are all far below millimeter wave burst pulse system.
So far, there is not yet the relevant report of the seeker-fuze integration receiving and transmitting front end being applicable to Millimeter Wave Pulsed system.
