It is to be understood that the objects so used may be interchanged where appropriate such that the embodiments of the present application described herein may be implemented in sequences other than those illustrated or described.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a flow diagram of an on-board interrogation fast beam scheduling method is shown, according to one embodiment of the present application.
As shown in fig. 1, a method of fast beam scheduling for on-board interrogation is shown, which is applied to an on-board interrogator that identifies a target based on a target signal scheduling beam transmitted by a radar; the method specifically comprises steps S100 to S300.
Step S100, a target sequence is established based on the radar transmitted information.
It will be appreciated that the radar is configured to scan for a target signal within a target area and to transmit the acquired target signal to the airborne interrogator; the airborne interrogator needs to identify the target scanned by the identification radar and judge whether the target is an enemy aircraft or a friend aircraft.
In some possible embodiments, based on the foregoing scheme, the establishing a target sequence based on the radar-transmitted information includes:
acquiring first target information of a target transmitted by a radar, wherein the first target information comprises a target batch number, a target distance and a target azimuth;
and establishing the target sequence according to the received first target information.
It will be appreciated that the radar will acquire the azimuth and distance information of the scanned target during scanning, and the target lot number is the number of the radar on the scanned target.
With continued reference to fig. 1, in step S200, the scheduling beam identifies the targets in the target sequence, and a buffer sequence is constructed in the identification process, where the buffer sequence refers to a sequence formed by all targets identified by a certain beam in the process of scheduling the certain beam to identify the certain target.
It will be appreciated that in identifying objects in the sequence of objects, the objects are identified one by one in a sequential order.
In some possible embodiments, based on the foregoing scheme, the scheduling beam identifies a target in the target sequence, including:
acquiring a target distance and a target azimuth of a target to be identified;
and scheduling the beam to identify the target based on the target distance and the target azimuth of the target.
In some possible embodiments, based on the foregoing scheme, the constructing the buffer sequence in the identifying process includes:
in the process of scheduling a certain beam to identify a certain target, acquiring all targets identified by the certain beam and acquiring second target information of all targets, wherein the second target information comprises target distance and target azimuth;
and establishing the cache sequence based on all the targets.
It will be appreciated that in the process of identifying each target by the scheduling beam, a buffer sequence is constructed to avoid subsequent repetition of the scheduling beam to identify the target.
For example, currently, the scheduling beam 1 identifies the target 1 in the target sequence, and a cache target 1, a cache target 2 and a cache target 3 are acquired in the identification process; at this time, the target distances and target orientations of the cache target 1, the cache target 2 and the cache target 3 are obtained, and a cache sequence is established.
With continued reference to fig. 1, step S300 identifies a target in the target sequence that is not subsequently identified based on the cached sequence.
It will be appreciated that the objects stored in the cache sequence are identified by the beam, and if the objects in the target sequence match the objects in the cache sequence, this indicates that the objects in the target sequence can be identified by the beam, and no further beam scheduling is required to identify.
In some possible embodiments, based on the foregoing solution, the identifying, based on the cached sequence, a target that is not identified subsequently in the target sequence includes:
matching the target which is not identified subsequently in the target sequence with the target in the cache sequence;
if the matching is successful, the target which is not identified subsequently in the target sequence is marked as identified.
For example, target sequence includes target 1, target 2, target 3, and target 4; in the process of identifying the target 1 by the scheduling beam 1, the acquired cache sequence comprises a cache target 1, a cache target 2 and a cache target 3, then in the subsequent target 2 and target 3 identification process, the target 2 and the target 3 in the target sequence are firstly matched with the cache target 1, the cache target 2 and the cache target 3 in the cache sequence, and if the matching is successful, the target 2 and the target 3 are marked as identified.
In some possible embodiments, based on the foregoing solution, the matching the target in the target sequence that is not subsequently identified with the target in the buffer sequence includes:
acquiring first target information of a target which is not identified subsequently in the target sequence;
acquiring second target information of a target in the cache sequence;
and matching the target which is not recognized subsequently in the target sequence with the target in the cache sequence based on the first target information and the second target information.
It may be appreciated that the first target information and the second target information both include a target azimuth and a target distance, and the target matching is implemented based on the target azimuth and the target distance, for example, if the target azimuth and the target distance of the target 2 can be matched with the target azimuth and the target distance of the cache target 2, it indicates that the cache target 2 is the target 2, and the matching of the target 2 and the target azimuth and the target distance is successful.
In summary, the method provided by the embodiment of the application avoids identifying the same target by repeated scheduling based on the established buffer sequence, improves the identification efficiency and reduces the wave beam scheduling times.
