Description
Technical field
The present invention relates to the spaceborne task management fields of Synthetic Aperture Radar satellite, and in particular to a kind of object-oriented synthesis
The intelligent spaceborne task management method of aperture radar satellite.
Background technique
Synthetic Aperture Radar satellite is a kind of remote sensing of the earth satellite with round-the-clock, round-the-clock detectivity, in disaster
Monitoring, environmental monitoring, marine monitoring, resource exploration, Crop Estimation, mapping and military affairs etc. using it is upper have it is unique
Advantage.As satellite is used widely in every field, demand of the user to Synthetic Aperture Radar satellite is not only to known
Static object " can be seen clearly " and functional requirements such as " seeing extensively " in region, and be to diversified in wide zone of ignorance
Target " can independently be seen " and applications demands such as " seeing fastly ".
The application process of Synthetic Aperture Radar satellite includes: to infuse data-on proposition demand-analysis imaging element-ground to defend
Star executes imaging-satellite backhaul data-processing imaging data, is completed by ground system and satellite system collaboration.Spaceborne task pipe
Reason method is the core methed of Satellite Management application process, using hardware resource and makes full use of software resource by unification, complete
At work such as whole star operational management, comprehensively control and information processings.In order to realize to target diversified in wide zone of ignorance " certainly
Master sees " and " seeing fastly " satellite application ability, it is desirable that spaceborne task management method implementation procedure is fastly, to cover process more, simultaneously
With autonomous analysis ability, ground system is relied on few.Therefore, autonomous, quickly, do not completely depend on intelligence of the people in circuit and appoint
Business management method is a technological difficulties in the spaceborne task management field of Synthetic Aperture Radar satellite.
The different content of " data are infused on ground ", existing spaceborne task management method are responded according to Synthetic Aperture Radar satellite
It can be divided into towards instruction class and oriented mission class.The control sequential of management method response system or single machine towards instruction class refers to
It enables；The management method of oriented mission class responds mission bit stream, and is autonomously generated, the control sequential instruction of arranging system or single machine
And parameter.The response data of two methods all must be by " proposing demand ", " analysis imaging element " and " infusing data " three on ground
Process, each process are mainly responsible for by ground system, it is desirable that professional operator directly or indirectly participates in, and requires ground
System is responsible for receiving " satellite backhaul data ", and completes " processing imaging data " process, it is seen that existing spaceborne task management method
Belong to passive type centralized control, although having the instruction of contexture by self part and parameter capabilities, the people being responsible for ground system
In circuit, dependence is stronger.
It is Polaroid not can be implemented simultaneously high-resolution and big breadth according to the image-forming principle of Synthetic Aperture Radar satellite,
Therefore, it is (hereinafter referred to as " wide to carry out big breadth low resolution imaging first for diversified target in the wide zone of ignorance of satellite sounding
Domain search imaging "), then carry out the small breadth imaging of high-resolution (hereinafter referred to as " fixed point recognition imaging ").Using existing spaceborne
Task management method not only requires to infuse mission bit stream on ground system, but also pinpoints the task of recognition imaging before imaging every time
Information needs to form " ground-satellite-ground-satellite-depending on the analysis result of ground system after wide area search imaging
Most short interval is imaged twice and reaches hour grade, greatly reduces the actual effect of wide area search information for the complex data stream process on ground "
Property, easily there is the case where fixed point identification target is lost, satellite system does not have discovery i.e. recognition capability.Existing synthetic aperture thunder
Up to satellite carried task management method be primarily present to people circuit dependence is big, task management it is intelligent it is low, cannot achieve hair
The technical issues of now identifying.
Through the retrieval to the prior art, application No. is 201510056210.7 Chinese invention patent disclose it is a kind of towards
The scattering pyramid classification method of polarimetric synthetic aperture radar image, comprising: the coherence matrix for reading in image to be classified is gone forward side by side
Row goes orientation process；Seek respectively target to preference parameter SDoPs, SDoPd of surface scattering, two area scatterings and volume scattering and
SDoPv and average preference's degree parameter SDoP3；Three layers of pyramid model are constructed based on SDoP3, three layers of pyramid model are the bottom of from
High, medium and low three kinds of scatterings random case is respectively represented to top；It, will based on the permutation and combination of parameter SDoPs, SDoPd and SDoPv
Three layers of pyramid model are divided into ten pieces, respectively indicate ten kinds of different scattering mechanisms；With different labels by image to be classified
It labels, forms final classification figure.But this method is complex, and operation difficulty is high, is unsuitable for being widely popularized and be applicable in.
Therefore, it is necessary to design, a kind of circuit is small to the dependence of people, task management intelligence degree is high, can be realized
It was found that the intelligent spaceborne task management method of the object-oriented Synthetic Aperture Radar satellite of i.e. identification.
