Abstract
The invention discloses a cloud-computing-based navigation radar working system architecture. The cloud-computing-based navigation radar working system architecture mainly comprises a single-machine navigation radar system, a self-assembly cloud computing radar system, and a maritime-satellite-network-based cloud computing radar system. A single radar can acquire surrounding target information through a cloud computing network, and compares and contrast the surrounding target information with target information which is acquired by a ship, so clutter and a target can be identified; and after the clutter is filtered out, accurate target information can be acquired. By predicting and computing the accurate target information, collision can be prevented accurately. Meanwhile, the radar scanning blind area of the ship can be compensated by the shared radar target information which is provided by surrounding ships, so large-range radar detection can be realized.

Technical scheme of the present invention is:
A kind of navar work system framework based on cloud computing, its job step mainly comprises 3 parts: first is the unit navigation radar system; Second portion is a self-assembly cloud computing radar system; Third part is based on the cloud computing radar system of marine satellite network.
The job step of described unit navar work system is following:
Step a: control unit radar carries out targeted scans;
Step b: radar target is extracted through the ARPA algorithm;
Step c: the course information that the positional information that cooperates this ship GPS to provide, compass provide etc. change into the radar target signal standard target form of unified coordinate system;
Steps d: through this ship satellite communication system or VHF (Very high frequency very high frequency(VHF): be meant that frequency band is by the radiobeam of 30 MHz to 300 MHz .) communication system with the standard target information broadcast to network;
Step e: search the dispatch server in the existing network, and accomplish corresponding Target Fusion;
Step f:, and download other target informations in this zone with the fusion goal upload server;
Step g: will merge target and this ship target and do the secondary fusion, and be presented on the screen.
The job step of described self-assembly cloud computing radar system is following:
Step a: the unit radar is at first surveyed the webserver in the annex zone through VHF;
Step b: judge whether that server is available: if the server of not built is then independently set up server, and the overseas broadcast server info; If have then location-server and connecting;
Step c: every unit radar carries out the ARPA target with the radar image that scans and extracts, and the position that provides according to external units such as GPS, compass then, azimuth information are carried out coordinate conversion, convert the target data under the standard format to;
Steps d: through VHF the target information under the standard format is uploaded to the clothes server, by server-assignment Target Fusion task;
Step e: after every unit is accomplished, share and merge target information;
Step f: again by the separate unit radar with fusion goal information, be presented on the screen.
The job step of described cloud computing radar system based on the marine satellite network is following:
Step a: the unit radar connects the cloud computing machine server of base station through existing maritime satellite system;
Step b～step e is identical with the job step c～step f of described self-assembly cloud computing radar system.
The invention has the beneficial effects as follows:
The present invention can significantly reduce the influence of clutter to radar target through the fusion of radar target information.
The present invention shares through target information, can increase the investigative range of radar, thereby further promote the detectivity of radar, reduces the blind area.
The present invention shares through radar target information, can know the accurate location information of ship on every side, and realize accurate collision prevention, has improved the security of navigation.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further description
:
As shown in Figure 1: as to the present invention is to provide a kind of navigation radar system framework based on cloud computing; Every unit radar is through communication networks such as satellite peculiar to vessel or VHF; Radar target information overseas broadcast with this ship; Again through organizing server certainly or utilizing the marine satellite network built that near the radar target signal of ship is merged; Every unit radar can be shared other radar target informations through this server platform again then, finally realizes sharing of radar target information, promotes the detection accuracy of unit radar.
The specific descriptions of the unit radar principle of work that relates among Fig. 1 are following: at first the unit radar carries out targeted scans; It extracts radar target through the ARPA algorithm; Cooperate the positional information that this ship GPS provides, the course information that compass provides etc. again, the radar target conversion of signals become the standard target form under the unified coordinate system, again through this ship prestige communication system or VHF communication system with standard target information broadcast to network; Search the dispatch server in the existing network simultaneously; And accomplish corresponding Target Fusion task, then with the fusion goal upload server, and download other target informations in this zone; At last fusion goal and this ship target are done secondary stack fusion, and be presented on the screen.
What Fig. 2 described is self-assembly cloud computing radar system; Specific descriptions are: self-assembly cloud computing radar system is fit to the boats and ships below 10,000 gross tons of coastal waters; These type of boats and ships generally be unworthy of getting everything ready marine satellite receive-transmit system of its communication ability relies on the VHF communication mode, sets up system for cloud computing certainly.The unit radar is at first sought the system for cloud computing server through VHF in the annex zone.If the server of not built is then independently set up server, and the overseas broadcast server info.If had server, then location-server and connection.Every single ship all with the radar scanning of this ship to radar image carry out the ARPA target and extract, the position that provides according to external units such as GPS, compass then, azimuth information are carried out coordinate conversion, convert the target data of the standard format under the unified coordinate system to.Through VHF the target information of standard format is uploaded onto the server; By server-assignment Target Fusion calculation task; After every unit radar is accomplished the Target Fusion task; Share and merge target information, the target information after will being merged by the unit radar again is presented on the display screen, for the user provides complete target information.
The cloud computing radar system that is based on the marine satellite network that Fig. 3 describes specifically describes as follows: the main framework based on the cloud computing radar system of marine satellite network and self-assembly cloud computing radar system is similar.Single ship connects the cloud computing server of base station through existing maritime satellite system, accomplishes the information sharing of radar target.This mode is relatively stable, and cloud computing server also can merge more target information, and can cooperate the supervision of competent authorities to corresponding marine site, is more suitable for the harbour of the above boats and ships of 10,000 gross tons and the big magnitude of traffic flow.
So far, the separate unit radar can obtain target information all around through system for cloud computing, and the target information that obtains with this ship compares fusion, can discern clutter and target, after the clutter filtering, can obtain accurate target information.Through target information is accurately predicted and calculated, can realize accurate collision prevention.Simultaneously, the shared radar target information through ship on every side provides can compensate the radar scanning blind area of this ship, realizes wider radar detection.So far, whole invention process finishes.
