Design method, it is ensured that with radar state uniformity.
(4) automatic error amendment
Automatic error amendment is exactly the feature using distributed radar system, by multiple receiving stations to same target
The method for carrying out resolution error is measured, multicycle accumulation analysis, automatic result of calculation is taken.
The present invention is applied by the way that the observation data of list portion radar in radar network are transformed into geocentric coordinate system (ECEF)
Generalized least-squares method (GLS) estimating system error, realizes the systematic features of radar network.
As shown in figure 4, N portions radar synchronization observes target location, the target location that these radar observations are arrived forms N
It is individual, these due to every radar systematic error and position is different, i.e., (Xi, Yi) | i=1 ... N }.Assuming that every thunder
The error reached for (Di, Wi) | i=1 ... N }, observation be adjusted to (Xi', Yi') | i=1 ... N }.Observation after adjustment
Point-to-point distance between value and cohesion distance is defined as, is designated as E.M such observation is carried out altogether, is obtained { (Xij, Yij)
| i=1 ... N j=1 ... M }, it is adjusted according to systematic error, obtain (Xij', Yij') | i=1 ... N j=
1 ... M, by this M times cohesion distance and ∑ Ej | j=1 ... M } be defined as correcting aim parameter T, it be (Di, Wi) | i=
1 ... N function.
Model assumption N portions radar can observe exhaustive every time, system is without random error with the same target of Synchronous.
In this case T->When 0, and (Di, Wi) | i=1 ... N } also tend to the solution of radar system error.
Observation can make the Ratage Coutpressioit of solution to the algorithm every time, and the effect of compression depends on target and radar in space
Distribution situation, is converged at error actual value with less amount of calculation, and the algorithm disclosure satisfy that the real-time of radar spatial registration
Property demand.Radar observation object delineation is as shown in Figure 4.
(5) coverage diagram is detected
System can generate the detectivity that radar coverage-diagram calculates radar, and reference value is provided for system.For determining
Radar system, its detection probability is the function of false-alarm probability and signal to noise ratio, i.e.,：
Pd=FCFAR(Pfa,SNR)
In formula, FCFAR() represent in different CFAR processing mode, the present invention on detection probability Pd, Pfa and
(SNR) relation between M three, quotes an empirical equation of research：
Wherein C0 is the decision parameter of radar performance, and C0 is about fallen with division, then be R for distance, RCS is σ target,
Its corresponding signal to noise ratio in radar receiver is：
So, signal to noise ratio is calculated with formula 1, then takes the different RCS of target, it is known that detection range R0, it is possible to calculate
Go out different detection range R.Radar management and control integrated radar detection area generation computational methods figure is as shown in figure 5, formula (1) in figure
That is formula (1), formula (3) is formula (3).
(6) different sensors is integrated
Single sensor is easily by various deceptions and interference, and the information that single-sensor is provided in performance can not yet
Operational need is met, the system is inherently integrated with several different types of radars, in future, radar management and control process even can be with
The multiclass detection means such as integrated electro detection, acoustic detection, electronic reconnaissance, low latitude gap-filler radar, and detection site is large number of.System
, can also be according to multiclass sensor performance on the basis of the collaboration detection in study of various detection resource respectively in itself of uniting is managed
Complementation, the detection mission of all kinds of detection resources of unified planning.

Signal to noise ratio is calculated with formula (1), the different Radar Cross Sections of target are then taken, it is known that detection range R0, R0As most
Big detectable distance, so as to calculate different detection ranges, according to all different detection ranges, obtains detecting coverage diagram.
4. a kind of foreign peoples's radar remote-control function integration system according to claim 1, it is characterised in that described information
Receive and receive the state report from radar with display module, be stored in database and shown, information is received and display
The working condition of all radars of module monitors, can carry out preview to radar information.
5. a kind of foreign peoples's radar remote-control function integration system according to claim 4, it is characterised in that the control
Module is by controlling all radars that message real-time control system is connected, and final power to make decision is at radar end, if radar end is not returned
Should, or refuse to be controlled, then control failure.
6. a kind of foreign peoples's radar remote-control function integration system according to claim 5, it is characterised in that the state
Interworking module is by the way of packet sending and receiving, cycle inquiry, treaty rule, it is ensured that the state at radar end and the report for accusing center-side
Text communication and state consistency.
7. a kind of foreign peoples's radar remote-control function integration system according to claim 6, it is characterised in that also including expanding
Module is opened up, expansion module adds new sensor by way of spare interface for system.
8. a kind of foreign peoples's radar remote-control function integration system according to claim 7, it is characterised in that described information
Receive and display module, display includes radar name, radar type, radar operation mode, current radar control form on interface
It has been shown that, the various status displays of current radar and all radar state tables；
Information is received with display module according to radar name determination radar type, then reads radar database, shows radar Working mould
Formula and user need the information checked.
9. a kind of foreign peoples's radar remote-control function integration system according to claim 8, it is characterised in that
The control module obtains the state of the primary radar, secondary radar and passive radar of current selected in real time, including：
Control module obtains the state of the primary radar of current selected in real time, when needing to control the state of current radar, adopts
With the mechanism of message response, state is sent to radar station, after the response message of radar station is received, according to the response shape of radar
State updates storehouse table, updates interface display；
Control module obtains the state of the secondary radar of current selected in real time, when needing to control the state of current radar, adopts
With the mechanism of message response, state is sent to radar station, after the response message of radar station is received, according to the response shape of radar
State updates storehouse table, updates interface display；
Control module obtains the state of the passive radar of current selected in real time, and order radar with a frequency band to a side
To detection.
10. a kind of foreign peoples's radar remote-control function integration system according to claim 9, it is characterised in that
The state interworking module inquired by the cycle, actively inquiry, text of first receiving telegraph write again storehouse, link re-prompted after disconnecting,
The method that Unknown is shown if state is not obtained, it is ensured that with radar state uniformity.
