Description
Technical field
When the present invention is multistation work, combines and consider that multistation is intercepted and captured for same radiation source, take into account multiple territories such as time, frequency and spatial domain to the constraint of dispatching algorithm simultaneously.The search of dispatching algorithm choose reasonable and tracking strategy, instant produce multistation passive phased-array radar application task and under related constraint condition efficient scheduled for executing, to reach the scheduling performance of optimum.
Background technology
Phased-array radar is the important new development of radar system one.It utilizes electromagnetic wave to be concerned with principle, changes the PHASE DISTRIBUTION on front, impel wave beam to realize electron scanning in space by certain rule, broken the restriction of normal radar mechanical scanning by program phase shift, has flexibly, the prompt antenna beam scanning ability become.Phased-array radar signal produces and Wave beam forming all adopts digitizing technique, has broken the limitation of conventional radar, and beam position and scheduling of resource control more flexible, thus can complete the several functions such as search and multiple target tracking simultaneously.Due to time, the resource-constrained such as frequency and energy of phased array radar system, just need to implement resource management effectively to phased-array radar, all kinds of resources of system just can be made reasonably to distribute between the task of search, multiple target following and other type, thus give full play to Phased Array Radars.The method for designing of Phased Array Radar Resource Scheduling strategy has multiple, adaptive scheduling algorithm can balance various radar event request required time, energy and computer resource in real time, for each scheduling interval selects a kind of dispatching method of one group of best radar sequence of events, be current for the most effective resource dispatching strategy of multifunction array radar.
Active radar and passive radar system not emitting electromagnetic wave itself, is passive reception work completely, can overcomes active shortcoming, has that operating distance is far away, the advantage of good concealment, has important effect for the viability of raising radar system under sophisticated electronic environment.Be applied in phased-array radar by passive detection technology, both can play the advantage of phased array, have again good counter-jamming characteristic, therefore the research of passive phased-array technique will have very important realistic meaning.
Passive Phased Array Radar Resource Scheduling mainly comprises passive search, tracking and task scheduling three partial content.The main task of passive search is to choose rational search parameter, makes to find that radiant source target is fast, find that radiant source target number is many, reaches optimum search performance.Passive phased-array radar searches for whole region successively according to programmed ripple bit sequence, can change the parameter adaptive of search mission according to actual conditions during search, so mainly comprise Beam Position Arrangement and parameter designing two aspect for the management of passive search.For above-mentioned two aspects, existing large quantity research both at home and abroad.Beam Position Arrangement is that passive phased array performs the basis of search mission, and passive search scans whole spatial domain successively according to programmed ripple bit table in advance just.Radiant source target is followed the tracks of, the least square method that 19 beginning of the century Gauss propose, start the basis of modern filtering, the forties in 20th century, the weiner equalizer that the people such as Wiener propose has established modern filtering theory, facilitate the development of single radiation source target following, after the sixties, along with developing rapidly of digital technology, filtering starts to become the major technique in radar data process, filtering applies in the tracking process of Mobile Pipeline target by the people such as Singer accordingly, propose the tracking of a series of Mobile Pipeline target, single radiation source target following technology is gradually improved.
To the research of the resident task scheduling of wave beam, adaptive resource dispatching algorithm is current the most effective a kind of dispatching algorithm, and research both at home and abroad at present mainly concentrates on the adaptive scheduling of active mode lower time, orientation and energy.Traditional dispatching algorithm based on pro-jobs level cannot know scheduler time load, and scheduling performance cannot promote, and in order to improve dispatching efficiency, a large amount of optimized algorithms is suggested in succession.To sum up the research of each side is all based on active phased array, does not send detection wave beam, only receive the signal from radiant source target radiation during passive phased-array radar work.Passive scheduling relies on radiant source target information, needs the combined dispatching strategy in time, orientation and frequency.Except managing to improve the dispatching efficiency of task from time, energy aspect, passive scheduling is also more emphasized by passive search and tracking strategy design application task and parameter thereof.Domestic less to research in this respect at present.
When the present invention works to multistation, combine and consider that multistation is intercepted and captured for same radiation source, take into account multiple territories such as time, frequency and spatial domain to the constraint of dispatching algorithm simultaneously.The search of dispatching algorithm choose reasonable and tracking strategy, instant produce multistation passive phased-array radar application task and under related constraint condition efficient scheduled for executing, to reach the scheduling performance of optimum.
Summary of the invention
The object of this technological invention is to provide a kind of general multistation federated resource scheduling and allocation algorithm, takes into account multiple territories such as time, frequency and spatial domain to the constraint of dispatching algorithm simultaneously.
When this technological invention emphasis solves multistation work, combine and consider that multistation is intercepted and captured for same radiation source, take into account multiple territories such as time, frequency and spatial domain to the constraint of dispatching algorithm simultaneously.The search of dispatching algorithm choose reasonable and tracking strategy, instant produce multistation passive phased-array radar application task and under related constraint condition efficient scheduled for executing, to reach the scheduling performance of optimum.
The technical scheme realizing this technological invention is:
First the multi-functional passive adaptive algorithm of multistation is determined, to the multi-functional passive adaptive scheduling task modeling of multistation.Passive task can be divided into search according to the difference of function, follow the tracks of and mistake such as to follow at the task, and different tasks has respective feature.Due to working method, comparatively active probe is low for passive search intercept probability.During passive detection, receiving front-end can regard a search window at Multidimensional signal spaces such as time domain, spatial domain, frequency domains as, and radiant source target signal is then the dynamic point in this space, only has this dynamic point to fall in this search window and just may intercept and capture.The object of scheduling is exactly reasonably arrange search mission, to improve the intercept probability of target, shortens the target detection time.
Tracing task will be proceeded to for the radiant source target found, because passive phased array can only detect the angle of radiant source target, least square method can be utilized to obtain angle change curve, use the constantly recursion correction of orientation tracking filter algorithm again, radiant source target tracking is carried out in prediction ripple position and radiant source target place frequency range when corresponding sampling interval, different radiant source target tracking accuracy requires different, and the tracking sampling cycle is also different.
If occurring in tracing process to follow the tracks of loses, then need initiation one to lose with task, lose in generation in precision allowed band and again search for target acquisition again with ripple position and radiant source target place frequency range.
