[0016] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] The first embodiment of the present invention provides a method for controlling an optoelectronic radar based on a targeting pod interface, such as Figure 1 As shown, the specific steps include: Step S1, obtaining the interface protocol of each command key of the aiming pod operation interface; In this embodiment, the interface protocol of the aiming pod operation interface includes target selection, target selection+, target selection-, adjustment item, adjustment item+, adjustment item-, snow plow, interception, laser radiation, follow-up LOS, follow-up coordinate point, manual search, and fixed axis.

[0019] Step S2, establishing a mapping relationship between each interface protocol and the working task of the photoelectric radar; In this embodiment, according to the interface protocol-work task form, the mapping relationship includes: follow-up LOS-follow-up radar, follow-up coordinate point-follow-up aiming line, snow plow-head display scanning, image stitching-long-range search, manual search-scanning and tracking, fixed axis-vertical scanning, interception-tracking target, laser radiation-laser radiation, adjustment item-azimuth search range or pitch search range adjustment, adjustment item+-azimuth search range or pitch search range increases in sequence, adjustment item-azimuth search range or pitch search range decreases in sequence, target selection-target selection, target selection+-target sequence number increases in sequence, target selection-target sequence number decreases in sequence, Step S3, determining the working mode according to the working task, and in the working mode, combining the mapping relationship, using the aiming pod operation interface to control the photoelectric radar to perform the working task; wherein the working mode includes a search mode and a staring mode, and the initial state of the aiming pod operation interface is the staring mode.

[0020] Specifically, since the aiming pod has only a staring mode as its working mode, the initial state of the aiming pod operation interface is the staring mode. The photoelectric radar has a working mode including a search mode and a staring mode, so the working mode needs to be switched to perform work tasks in the working mode.

[0021] Since the aiming pod’s main action range is to the ground, the detection center usually follows other sensors or waypoints, and the adjustment amount is small and there are few opportunities for adjustment. The main action range of the photoelectric radar is to the air, and the adjustment range is large and the adjustment probability is high. Therefore, the original method of adjusting the detection center of the carrier aircraft cannot be used for the head compartment of the photoelectric radar. The detection center needs to be adjusted according to the common mission range of the photoelectric radar.

[0022] Step S31, taking the zero position of the machine system as the detection center, and adjusting the detection center of the photoelectric radar when receiving an instruction of a detection position change, the adjustment formula is:

[0023]

[0024] In the formula, a is the detection center of the photoelectric radar, The position of the aircraft direction control key before moving. is the azimuth movement rate coefficient of the aircraft direction control key, is the azimuth movement rate of the aircraft direction control key, b is the detection elevation center of the photoelectric radar, This is the pitch of the aircraft before the direction control key is moved. is the pitch movement rate coefficient of the aircraft direction control key, The aircraft direction control key is the pitch movement rate of the aircraft. The aircraft direction control key of this embodiment is a cursor on the aircraft.

[0025] The switching of working modes and the adjustment of the detection center are realized by the main control module of the photoelectric radar. After pressing the interface command key, the task system sends a command to the photoelectric radar according to the interface protocol. After receiving the command, the main control module of the photoelectric radar converts it into the corresponding work task according to the mapping relationship, and runs the working mode switching and detection center adjustment functions.

[0026] Step S32, determine the working mode according to the working task. When the working mode is determined to be the staring mode, obtain the infrared video, process the infrared video, obtain a composite video containing characters, send the composite video to the carrier mission system, and the carrier mission system displays the composite video on the operation interface; after receiving the interception command, the photoelectric radar tracks the target closest to the detection center.

[0027] When performing the tasks of the follow-up radar and the follow-up aiming line, the optoelectronic radar compartment uses the staring mode to detect the designated position in a small range, and the output video changes little. Specifically, the infrared video output by the infrared detector is filtered to obtain a digital video. In the digital video, the pixel gray value is set to 255 / 0 to superimpose characters to form a composite video. The characters include the working mode and target information. The composite video is displayed on the aiming pod operation interface, see Figure 2 . Figure 2 In the figure, the character "optical mine" means that the current working product is optoelectronic radar, the character "following aiming line" means that the current working mode is following aiming line, the character "ranging" means the laser radiation command, the character "setting" can enter the secondary interface to make settings such as "adjustment items", the character "range: 2,2" means that the current field of view is 2°x2°, the character "center: -30,2" means that the current azimuth following center is -30° and the pitch following center is 2°, the character "target: -30.2, 1.7" means that the target's azimuth is -30.2° and the pitch angle is 1.7°.

[0028] Among them, the staring function is completed by the main control module, infrared module and image module of the optoelectronic radar. The main control module realizes the analysis of the intercepted instructions and controls the product to enter tracking. The infrared module obtains the infrared video detected by the infrared detector in the optoelectronic radar. The image module processes the infrared video and superimposes characters.

[0029] Step S33, when it is determined that the working mode is the search mode, the detection video of the entire field detection of the photoelectric radar is obtained, and the video of the target appearing in the detection video is intercepted to obtain the target video; the target position and the status information of the photoelectric radar are obtained, and sent to the carrier mission system, and the carrier mission system displays the target video, target position and the status information of the photoelectric radar on the operation interface; and after receiving the interception instruction, according to the mapping relationship, the corresponding instruction key (target selection) is controlled to select the target position on the operation interface to track the target.

[0030] Specifically, when performing HUD scanning, long-range search, scanning and tracking, and vertical scanning tasks, the optoelectronic radar compartment uses a large-scale scanning method to quickly search the designated area, and the operation interface uses a search mode for display. Due to the large amount of output video, the video cannot be displayed in real time, and multiple targets will be found in one search. This embodiment uses target video + character overlay for display. This embodiment takes 8 targets as an example for a specific introduction.

[0031] Get all the videos of each search, intercept the videos where the target appears, where the size of a single video is no larger than 1 / 24 of the operation interface. If there are more than 8 targets, intercept the current frame videos of the 8 targets with high priority according to the target priority; display the 8 target videos, target positions and the status information of the photoelectric radar on the operation interface. Furthermore, spatial simulation characters can be drawn based on the coordinates of the current detection center, detection range and target position, and the 8 target videos and spatial simulation characters can be combined to obtain a composite video, which is displayed on the operation interface.

[0032] Search operation interface Figure 3 , the upper part is the target video display area, the middle part is the space simulation character display area, and the lower part is the target position display; the function of the command key on the left is target selection, including target selection, target selection + and target selection -. The first target is selected by default. If you press target selection +, the main control software of the optoelectronic radar compartment will increase the target number by 1 according to the mapping table, and select targets to the right in turn. If you press target selection -, you will select targets to the left in turn; after selecting the target, the selected target is marked in the target video display area with superimposed shadow characters, and in the space simulation character display area with black marking. The function of the command key on the right is search range adjustment, including adjustment item, adjustment item + and adjustment item -. Press the search range, and the characters "search range azimuth" and "search range pitch" are alternately displayed by character superposition according to the mapping table. By pressing the adjustment item + and adjustment item - buttons, the azimuth search range or pitch search range can be adjusted.

[0033] Among them, the search function is completed by the main control module, follow-up module, infrared module and image module of the optoelectronic radar. The main control module realizes the working mode switching, target position calculation, target selection, and adjustment item solution functions; the follow-up module controls the product to search; the infrared module obtains infrared video; the image module intercepts the target video and superimposes the target position and status information.

[0034] Step S34, in the initial detection state, control the corresponding command key (laser radiation) to turn off the radiation laser of the photoelectric radar; and in the tracking process, when receiving the command to start radiation, control the corresponding command key to make the photoelectric radar radiate laser.

[0035] In this embodiment, the main task of the aiming pod is to illuminate the ground and measure the distance, and the laser radiation control is closely related to the state of the carrier aircraft; the main task of the photoelectric radar is to measure the distance of small targets in the air. Therefore, when controlling the photoelectric radar, first control the corresponding command key to turn off the radiation laser of the photoelectric radar. If it needs to be started during the tracking process, control the corresponding command key to make the photoelectric radar radiate the laser to ensure the safety of the photoelectric radar.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
