Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of aerial target indication and shooting decision systems, and in particular to an aerial target indication and auxiliary shooting decision method. Background Art
[0002] Without target indication and auxiliary shooting decision, portable missile shooters mainly search for targets through manual visual search, and shoot after finding the target by estimating the shooting parameters and judging by experience. The probability of finding the target by visual means is low, the distance is short, and the shooter has a short preparation time. Estimating the shooting parameters, judging the target's entry and exit of the launch area, and grasping the timing of the launch are all high requirements and difficult for the shooter. These factors restrict the target hit rate of portable missiles. At present, optical sights, infrared night vision sights or command information systems are usually added to solve these problems.

[0042] The preferred embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present disclosure can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present disclosure.
[0043] See also Figure 1 As shown, an aerial target indication and auxiliary shooting decision method comprises:
[0044] S1. Obtain situational awareness information and obtain the missile's kill zone;
[0045] 1. Gain situational awareness information
[0046] The air situation access unit can obtain situational awareness information indirectly by connecting with the intelligence center, and can also obtain situational awareness information directly by connecting with radar and infrared search equipment. The situational awareness information includes the altitude, speed, distance and coordinate values of air targets.
[0047] 2. Obtain the missile's kill zone
[0048] 1) Establish a kill zone airspace model
[0049] The kill zone is a comprehensive performance indicator. In this airspace, the missile can kill the aerial target with a probability not less than a given one. For portable missiles, the kill zone is determined by factors such as the maximum kill slant range, minimum kill slant range, maximum kill altitude, minimum kill altitude, maximum launch angle and maximum route angle.
[0050] The spatial kill zone is divided into a vertical plane kill zone and a horizontal plane kill zone for analysis. The vertical plane kill zone is obtained by cutting with the zero-route shortcut as the longitudinal section, and the horizontal plane kill zone is obtained by cutting with the horizontal plane where the target is located.
[0051] See also Figure 2 As shown, x is the horizontal coordinate axis, H is the vertical coordinate axis, the upper boundary ab and the lower boundary cd of the killing zone are parallel to the x-axis, and the distances from the x-axis are the maximum killing height and the minimum killing height, respectively. The far boundary bc and the near boundary ed of the killing zone are respectively based on 0 as the origin and the maximum killing slant distance D y , minimum killing slant range D j The killing zone is near the boundary ae, and its corresponding parameter is the maximum launch angle θ that can kill the target. max .
[0052] See also Figure 3 As shown, x is the horizontal coordinate axis and z is the lateral coordinate axis. The far boundary fg of the killing zone can be approximated as a circular arc with the projection of the maximum killing slant range on the horizontal plane as the radius. The lateral boundaries kf and ng of the killing zone correspond to the maximum path angle R that can kill the target. max , arc kn is the near boundary of the killing zone, P y is the maximum route shortcut to the far edge of the kill zone, P j is the maximum route shortcut near the kill zone, P M It is a shortcut to the target, Q M is the heading angle of the target motion.
[0053] 2) Determine the kill zone
[0054] The killing zone of portable missiles adopts different heights (height range: H min~H max ) is characterized by the horizontal killing zone.
[0055] See also Figure 2 and Figure 3 As shown, when the target is flying at an altitude of H(H min <H<H max )hour:
[0056]
[0057] Let the height of point e be H e , then H e =D j sinθ max .
[0058] When H min <H≤H e hour:
[0059]
[0060] When H e <H≤H max hour:
[0061] d j =Hcotθ max
[0062] Therefore, the coordinates of the characteristic points f, g, k, and n in the horizontal killing zone with a height of H are:
[0063] f(d y cosR max , d y sinR max ), g(d y cosR max , -d y sinR max ), k(d j cosR max , d j sinR max ), n(d j cosR max , -d j sinR max ), determine the shape of the kill zone based on the kill zone feature points.
[0064] S2, based on the situation awareness information and the kill zone of the missile, obtaining the missile's attack launch zone or tail pursuit launch zone. In this step, a route shortcut of the air target can also be obtained;
[0065] Based on the coordinates of the characteristic point f in the kill zone and the average speed of the missile, the time t from the missile launch to the flight to point f is calculated. f , calculate the average speed V of the target based on the speed of the target at the last four time points f Move S from the kill zone in the opposite direction of the target's heading f Distance (S f =V f t f ), the F point corresponding to the launch area is obtained. After the launch area G, K, and N points corresponding to the characteristic points g, k, and n of the kill zone are obtained in the same way, the launch area at the height H is determined. The launch area is divided into the attack launch area and the tail chase launch area.
[0066] 1) Determine the attack launch area
[0067] See also Figure 4 As shown, the black circle M is the flying target, t f is the time it takes for the missile to fly to point f from launch, V f is the average speed of the missile flying to point f, t n is the time it takes for the missile to fly to point n from launch, V n It is the average speed of the missile flying to point n. The area composed of points f, g, k, and n as vertices is the killing zone, and the area composed of points F, G, K, and N as vertices is the attack launch zone.
[0068] 2) Determine the tail-chasing launch area
[0069] See also Figure 5 As shown, the black circle is the flying target, t k is the time required for the missile to fly to point k from launch, V k is the average speed of the missile flying to point k, t f is the time it takes for the missile to fly to point f from launch, V f It is the average speed of the missile flying to point f. The area formed by points f, g, k, and n as vertices is the killing zone, and the area formed by points F, G, K, and N as vertices is the tail pursuit launch zone.
[0070] 3) Determine the route shortcut to the air target
[0071] See also Figure 3 As shown in the figure, the target heading angle Q is obtained by fitting a straight line based on the coordinate parameters of the target at the last four time points. M , and obtain the target route shortcut P M =d y q M .
[0072] S3, based on the missile's attack launch area or tail launch area, and the air target's route shortcut, the missile's precise aiming area, launch area, and launch timing are obtained and displayed on the aiming device. In this step, the missile's battery start-up and unlocking information can also be obtained and displayed on the aiming device.
[0073] See also Figure 6 , Figure 7 As shown, the display on the sighting device includes:
[0074] On the shooting decision display interface of the aiming device, a timeline based on the launch area is displayed. On the timeline, it can start from 0. The battery start line, unlocking line and launch line are displayed in sequence on the timeline, and the position of the aerial target on the timeline is displayed in real time.
[0075] In the above step S3, there is a display during a head-on attack and a display during a rear-end collision.
[0076] See also Figure 6 As shown, when attacking;
[0077] 1) Determine the range of the missile launch area
[0078] Based on the distance from the aerial target to the far boundary of the oncoming launch zone and the average speed of the aerial target, the time when the aerial target passes through the far boundary of the oncoming launch zone is obtained; based on the distance between the far boundary of the oncoming launch zone and the near boundary of the oncoming launch zone and the average speed of the aerial target, the time when the aerial target leaves the near boundary of the oncoming launch zone is obtained;
[0079] Based on the time when the aerial target passes through the far boundary of the oncoming launch zone and the time when the aerial target leaves the near boundary of the oncoming launch zone, the interval of the missile oncoming launch zone is displayed on the time axis.
[0080] 2) Determine the battery start line
[0081] Based on the distance from the aerial target to the far boundary of the oncoming launch zone and the average speed of the aerial target, a battery start line is set 10 to 15 seconds before the aerial target enters the missile oncoming launch zone.
[0082] 3) Determine the unlock line
[0083] The unlocking line may be set at the initial position of the attack launching area;
[0084] 4) Determine the emission line
[0085] After the aerial target enters the oncoming launch area, the launch line is set based on the average speed of the aerial target.
[0086] 5) Determine the precise targeting area
[0087] The missile precision aiming area is located on the time axis and extends from the battery start line to the launch line.
[0088] When the aerial target moves from right to left to the battery start line, it means that the battery should be started immediately. At the same time, the target falls into the precise aiming area, prompting the shooter to accurately aim and track the aerial target. When the aerial target moves to the unlocking line, it means that the seeker should be unlocked. When the aerial target moves to the launching line, the shooter can combine the sound and light signals to make a launching action.
[0089] See also Figure 7 As shown, in the case of tailgating;
[0090] 1) Determine the range of the missile launch area
[0091] Based on the distance from the aerial target to the near boundary of the tail pursuit launch zone and the average speed of the aerial target, the time when the aerial target passes through the near boundary of the tail pursuit launch zone is obtained; based on the distance between the near boundary of the attack launch zone and the far boundary of the attack launch zone and the target average speed of the aerial target, the time when the aerial target leaves the far boundary of the tail pursuit launch zone is obtained;
[0092] Based on the time when the aerial target passes through the near boundary of the tail pursuit launch zone and the time when the aerial target leaves the far boundary of the tail pursuit launch zone, the interval of the missile tail pursuit launch zone is displayed on the time axis.
[0093] 2) Determine route shortcut signs
[0094] Based on the distance from the aerial target to the aerial target route shortcut and the average speed of the aerial target, the time for the aerial target to pass through the aerial target route shortcut is obtained, and a route shortcut mark is displayed on the time axis.
[0095] 3) Determine the battery start line
[0096] Based on the air target speed, a battery start line is set 8 to 10 seconds before the air target passes through the air target route shortcut.
[0097] 4) Determine the unlock line
[0098] The unlocking line may be arranged at an initial position of the tail-chasing launch zone.
[0099] 5) Determine the emission line
[0100] After the aerial target enters the tail-chasing launch area, the launch line is set based on the speed of the aerial target.
[0101] 6) Determine the precise aiming area
[0102] The missile precision aiming area is located on the time axis and extends from the battery start line to the launch line.
[0103] When the aerial target moves from right to left to the battery start line, it means that the battery should be started immediately. At the same time, the target falls into the precise aiming area, prompting the shooter to accurately aim and track the aerial target. When the aerial target moves to the unlocking line, it means that the seeker should be unlocked. When the aerial target moves to the launching line, the shooter can combine the sound and light signals to make a launching action.
[0104] In traditional aiming and shooting, the shooter needs to complete a series of actions in a short time, including target search, shooting parameter estimation, battery startup, target aiming and tracking, seeker unlocking, and launch. In this process, the shooter needs to make correct judgments in a very short time, including estimating the launch start parameters, selecting the missile working state, and judging the target entering and leaving the launch area. This is very demanding and difficult for the shooter.
[0105] The disclosed aerial target indication and auxiliary shooting decision method can guide the shooter to find and lock the target in advance during the stage of searching and discovering the target, providing the shooter with sufficient preparation time. In the stages of target tracking, aiming and launching, it can provide the shooter with shooting decisions, effectively improving the combat capability of portable missiles.
[0106] In another embodiment of the present disclosure, during the stage of searching and finding the target, the shooter can guide the search, finding and aiming at the aerial target in advance through the instructions on the aiming device, and the specific method is:
[0107] In step S1, obtaining situational awareness information also includes: calculating the azimuth and elevation of the aerial target through the coordinate value of the aerial target, collecting the posture information of the cartridge through a posture sensor, comparing the posture information data of the aerial target and the cartridge, representing the comparison result in the form of an arrow, and displaying it on the aiming device, and the shooter follows the arrow instructions to guide the shooter to search, find and aim at the aerial target.
[0108] 1) Calculate the azimuth of the aerial target
[0109] See also Figure 8 As shown, the coordinate values of the aerial target are based on the values in the Gaussian plane rectangular coordinate system. Point A is the coordinate of the shooter, obtained through the Beidou device, and point B is the coordinate of the aerial target. Δx AB is the vertical increment from point A to point B, Δy AB It is the horizontal coordinate increment from point A to point B.
[0110] AB is the projection of the line connecting the shooter and the aerial target on the horizontal plane, and its length is d. Then:
[0111]
[0112] Angle
[0113] The azimuth angle β is based on the following table:
[0114] The following table is the azimuth angle β value table
[0115] <![CDATA[Δx AB ]]> <![CDATA[Δy AB ]]> Quadrant Azimuth angle β value + + Quadrant 1 α － + Second Quadrant 180-α － － The third quadrant 180+α + － Quadrant 4 360-α
[0116] Based on the above method, the azimuth of the aerial target is calculated.
[0117] 2) Calculate the pitch angle of the aerial target
[0118] See also Fig. 9 As shown, point A is the coordinate of the shooter, and point B is the coordinate of the aerial target. The height of point A is h1, the height of point B is h2, and the height of the aerial target relative to the shooter is h3=h2-h1.
[0119] The projection distance of the line connecting the shooter and the aerial target on the horizontal plane is d, then:
[0120] Pitch Angle
[0121] The pitch angle of the aerial target can be calculated using the above method.
[0122] 3) Collecting missile attitude information
[0123] The attitude sensor installed on the barrel collects the attitude information of the barrel. The attitude sensor has an embedded electronic compass and can collect the real-time azimuth, pitch and roll information of the missile. When in use, keep the roll angle at about 0° to read the pitch and azimuth data.
[0124] 4) Posture data comparison
[0125] The azimuth and elevation angle values of the aerial target and the cartridge are compared.
[0126] 5) Guide the shooter to search, discover and aim at aerial targets
[0127] The aiming cursor is displayed on the aiming device, and the aiming cursor also has an arrow pointing to the direction of the air target. The pitch angle and azimuth of the target and the missile can also be displayed on the aiming device for easy comparison; the aiming cursor can be a cross cursor.
[0128] See also Fig.10 As shown, the aerial target is in the upper left area of the current cartridge posture, and the shooter needs to move the cartridge to the upper left to search for the target according to the arrow indication.
[0129] See also Fig.11 As shown, the aerial target is in the lower right area of the current cartridge posture, and the shooter needs to move the cartridge to the lower right to search for the target according to the arrow indication.
[0130] See also Fig.12 As shown, after the shooter adjusts the barrel posture according to the arrow indication, the aerial target is aimed and locked. At this time, the arrow on the aiming cursor disappears, and the elevation and azimuth values of the barrel and the aerial target are equal.
