Figure 901459DEST_PATH_IMAGE003
in the formula:Hthe unit of time consumed by each circle of machine scanning of the radar is second;αis from the first toNThe horizontal angle of each beam to the (N + 1) th beam is in degrees;Iis the search beam dwell time in seconds;
and secondly, the radar master control scheduling system is overlapped with master control software through a sliding time window algorithm to realize the self-adaptive scheduling of the radar master control:
assume that the actual scheduling interval is

in summary, the time window

The update expressible formula is:

referring to the above equation (2), the burst scheduling task can be processed, and the details of the processing are as follows:
1) when the burst scheduling task is less, then
Figure 83259DEST_PATH_IMAGE014
Is less than
Figure 153983DEST_PATH_IMAGE015
Time window
Figure 941810DEST_PATH_IMAGE016
Will increase
Figure 781590DEST_PATH_IMAGE017
；
2) When there are more burst scheduling tasks, then
Figure 731092DEST_PATH_IMAGE018
Is greater than
Figure 289112DEST_PATH_IMAGE019
Time window
Figure 303467DEST_PATH_IMAGE020
Will reduce
Figure 997753DEST_PATH_IMAGE021
；
When the radar rotates clockwise, the corresponding horizontal electric scanning angle
Figure 383735DEST_PATH_IMAGE022
Clockwise direction is positive and negativeThe hour hand direction is negative; when the time window
Figure 163472DEST_PATH_IMAGE023
To correct the time, the electric sweeping angle

Is positive, otherwise the angle is electrically swept

The conversion is carried out by the following formula:
Figure 786084DEST_PATH_IMAGE024
Figure 189383DEST_PATH_IMAGE025
limiting a time window
Figure 182747DEST_PATH_IMAGE026
In the range of
Figure 405918DEST_PATH_IMAGE027
When the time window is set
Figure 565766DEST_PATH_IMAGE028
In that
Figure 89151DEST_PATH_IMAGE029
Horizontal azimuth electrical scan angle of scanned beam during internal change

Will also be in
Figure 229463DEST_PATH_IMAGE031
Change in the same direction and with
Figure 239007DEST_PATH_IMAGE032
The absolute value of the search beam is increased, in order to keep the search power unchanged, the pulse number of the arranged search beam is correspondingly increased, and the dwell time of the search beam is correspondingly increased;
thirdly, the radar master control scheduling system judges whether the current system resources are sufficient through a preset early warning threshold:
in equation (1), the beam dwell time is searched
Figure 600587DEST_PATH_IMAGE033
Will result in
Figure 935753DEST_PATH_IMAGE034
Reduction of time until
Figure 336779DEST_PATH_IMAGE035
Is close to 0; when the time window
Figure 415593DEST_PATH_IMAGE036
Slide rightward and gradually approach
Figure 647992DEST_PATH_IMAGE037
When it comes to
Figure 419639DEST_PATH_IMAGE038
Approaching 0, even without scheduling a burst schedule, does not result in a time window
Figure 589851DEST_PATH_IMAGE039
Continuing to increase; when time isWindow (Refreshment window)
Figure 472356DEST_PATH_IMAGE040
Slide leftward and gradually approach
Figure 496944DEST_PATH_IMAGE041
Will also result in
Figure 439492DEST_PATH_IMAGE042
Approaching 0, if this occurs, would result in a time window
Figure 346268DEST_PATH_IMAGE043
After sliding to the right, the sliding is irreversible, and subsequent burst residency cannot be arranged; in order to avoid the irreversible time window sliding to the right, 1 insufficient early warning threshold is set
Figure 766886DEST_PATH_IMAGE044
Resulting in horizontal electrical orientation after burst parking scheduling
Figure 223144DEST_PATH_IMAGE045
Is located at
Figure 805435DEST_PATH_IMAGE046
And
Figure 730665DEST_PATH_IMAGE047
in between, the search beam dwell time needs to be limited
Figure 627077DEST_PATH_IMAGE048
In extreme cases, even the residence time of the search beam needs to be reduced, and meanwhile, the alarm of insufficient system resources is reported so as to realize the rapid recovery of the system resources;
and fourthly, reporting the result of the residual time resource in the sliding time window obtained by the analysis in the first step to the third step to display and control software of a sliding time window algorithm by the radar master control scheduling system:
on the main control software of the radar, when the self-adaptive scheduling is realized, the residual time resources in the sliding time window are reported to the display control software in real time; meanwhile, if the current sliding time is insufficient and the self-adaptive scheduling requirement cannot be met, reporting an insufficient resource alarm, displaying an alarm real-time state on a display controller, and simultaneously supporting the inquiry of a historical alarm state;
and fifthly, displaying the current use condition of the radar master control resource by the display control software in a display mode of a sliding window or an instrument panel:
the state monitoring interface and the control interface of the radar self-adaptive resource scheduling of the radar display and control software are used for realizing the dynamic display and adjustment of the scheduling state of the master control resource, and the display and control interface visually displays the current resource utilization rate of the radar in real time;
sixthly, operating the display control software by a radar operator, combining the use condition of the radar resource and the sliding time accumulated in the radar searching process, scheduling the task and then transmitting the task to the main control software to realize the dynamic scheduling and adjustment of the main control resource;
and the first step to the sixth step are a radar self-adaptive resource scheduling and visualization control unit, and after the radar self-adaptive resource scheduling and visualization control unit is completed, the first step to the sixth step are repeated to complete the next unit until the radar task is completed.
