and step three, calculating the maximum distribution suspension depth of the suspended interception bomb 3 when the upper bound of the vertical boundary of the bomb array of the suspended interception bomb 3 is the upper bound of the interception range.
In step one, the general torpedo 1 starts to climb when finding a target and starting an attack. The climbing aiming point is different due to the difference of guidance types of the incoming torpedoes 1, and the position of the surface ship 2 is simplified and treated as the point.
In the second step, after the surface ship 2 gives an alarm to the torpedo 1, the incoming torpedo 1 is at a depth position of not less than 40m and sails in alignment with the position of the surface ship 2, and the surface ship 2 is in front of the path of the torpedo 1; and when the ammunition launching reference position of the surface ship 2 is consistent with the alarm sonar detection reference position of the torpedo 1, the surface ship 2 launches the suspension type intercepting bullets 3 to carry out arraying interception.
Further, in the second step, when the lower bound of the vertical boundary of the missile array of the suspension type interception missile 3 is the lower bound of the interception range, the minimum deployment suspension depth of the suspension type interception missile 3 is calculated:
when L is less than or equal to D1, namely the torpedo 1 starts to climb, the horizontal distance between the torpedo 1 and the surface ship 2 is not less than the distribution distance of the suspended intercepting bullets 3; the depth of the torpedo 1 is continuously reduced along with the climbing, namely H3/H2 is L/D1, and the minimum laying suspension depth of the suspension type interception bomb 3 is as follows:

when D1 < L, promptly the torpedo 1 begins to climb, the horizontal distance between torpedo 1 and surface ship 2 is less than the distance of laying of floated interception bullet 3, then the minimum laying suspension degree of depth of floated interception bullet 3 is:
h ═ H1+ H2-R, wherein: d1 is the horizontal distance from the water surface ship 2 when the torpedo 1 starts to climb; l is the horizontal distance between the bomb array arrangement position of the suspended intercepting bomb 3 and the surface ship 2; h is the minimum laying suspension depth of the suspension type interception bomb 3; h1 is the draft of the surface vessel 2; h2 is the depth difference between the depth of the navigation before the torpedo 1 climbs and the depth of the bottom of the surface ship 2; r is the damage radius of the suspension type interception bomb 3.
In the second step, the lower bound of the vertical boundary of the bomb array of the suspended interception bomb 3 is the maximum depth value which can be covered by the interception area of the suspended interception bomb 3 in the actual interception process, and the lower bound of the interception range of the suspended interception bomb 3 is the maximum depth value which is clearly covered by the interception area of the suspended interception bomb 3 in the theoretical design.
And in the third step, when the upper bound of the vertical boundary of the bomb array of the suspension type interception bomb 3 is the upper bound of the interception range, calculating the maximum distribution suspension depth of the suspension type interception bomb 3:
when L is less than or equal to D1, namely the torpedo 1 starts to climb, the horizontal distance between the torpedo 1 and the surface ship 2 is not less than the distribution distance of the suspended intercepting bullets 3; the depth of the torpedo 1 is continuously reduced along with the climbing, namely H3/H2 is equal to L/D1, and the maximum laying suspension depth of the suspension type interception bomb 3 is as follows:
h is H1+ L/D1 multiplied by H2+ R, or H is H1+ L multiplied by tan theta + R, wherein L is the horizontal distance from the bomb configuration position of the suspension type intercepting bomb 3 to the surface ship 2, and D1 is the horizontal distance from the surface ship 2 when the torpedo 1 starts climbing; h3 is the difference between the depth of the upper boundary of the suspended interception bullet 3 bullet array and the depth of the bottom of the surface ship 2 when the upper boundary of the suspended interception bullet 3 bullet array boundary is consistent with the upper boundary of the interception range; h2 is the depth difference between the depth of the navigation before the torpedo 1 climbs and the bottom depth of the surface ship 2; h is the maximum laying suspension depth of the suspension type interception bomb 3; h1 is the draft of the surface vessel 2; r is the damage radius of the suspension type interception bomb 3; theta is a climbing angle when the torpedo 1 is switched into a climbing stage;
when D1 < L, promptly the torpedo 1 begins to climb, the horizontal distance between torpedo 1 and surface ship 2 is less than the distance of laying of floated interception bullet 3, then the maximum laying suspension depth of floated interception bullet 3 is:
h ═ H1+ H2+ R, where: d1 is the horizontal distance from the water surface ship 2 when the torpedo 1 starts to climb; l is the horizontal distance between the bomb array arrangement position of the suspended intercepting bomb 3 and the surface ship 2; h is the minimum laying suspension depth of the suspension type interception bomb 3; h1 is the draft of the surface vessel 2; h2 is the depth difference between the depth of the navigation before the torpedo 1 climbs and the depth of the bottom of the water surface ship 2; r is the damage radius of the suspension type interception bomb 3.

In the third step, the distribution distance of the suspended intercepting bomb 3 is the horizontal distance between the position of the drop point of the suspended intercepting bomb 3 and the launching point of the surface ship 2.
Meanwhile, the method can support the demand analysis of the suspension depth of the interception bomb, improve the accuracy and effectiveness of the suspension depth of the distribution of the interception bomb, theoretically cover the navigation depth of the incoming torpedo 1, support the analysis and research of the operational use and operational efficiency of the suspension interception bomb 3, and provide support for the design and capability evaluation of the anti-torpedo 1 operational weapon system of the surface ship 2.
The method considers main factors such as the terminal navigation characteristic of an incoming torpedo 1 route, the physical characteristic of a surface ship 2, the damage characteristic of a suspended intercepting bomb 3 and the like, and calculates the distribution depth of the suspended intercepting bomb 3 according to the relative position relation of the main factors.
For the method, the following description specifically explains the calculation of the suspension depth of the small-caliber suspension type interception bomb 3 as an example:
(1) setting parameters:
the navigation depth of the incoming torpedo 1 before climbing is about 60 m; the climbing angle of the incoming torpedo 1 is about 1.5 degrees; the draft of the surface vessel 2 is about 6 m; the farthest arrangement distance of the small-caliber suspension type interception bomb 3 is about 1200 m; the damage radius of the small-caliber suspension type interception bomb 3 is about 14 m;
(2) calculating the minimum arrangement depth of the suspended interception bomb 3:
the climbing angle of the torpedo 1 is generally small, the range of 1-2 degrees is large, and the value of D1 is larger than the value of L; therefore, the minimum levitation depth of the levitation type interceptor projectile 3 can be obtained by applying the above formula to calculate respectively: h is 23 m;
(3) calculating the maximum arrangement depth of the suspended interception bomb 3:
according to the method, the maximum suspension depth of the suspension type interception bomb 3 is calculated as follows: h is 51 m.
Therefore, under the condition of setting parameters, the range of the arrangement suspension depth of the suspension type interception bomb 3 is 23-51 m.
Due to the fact that the damage radius of the small-caliber suspension type intercepting bullet 3 is small, in order to reduce the phenomenon that two adjacent suspension type intercepting bullets 3 are wound underwater due to too deep suspension, and meanwhile, in the using process, the intercepting bullet arrays are difficult to ensure that all the intercepting bullets are distributed at the far boundary of the action range, through analysis, the minimum suspension depth of the suspension type intercepting bullet 3 is determined to be properly reduced to be about 18 m.
In the practical application process, factors such as the length and the width of the platform can be considered by combining the navigational speed, the course and the azimuth relation of the surface ship 2 and the incoming torpedo 1, the suspension depth of the suspension type intercepting bomb 3 is properly adjusted, the navigation depth of the incoming torpedo 1 is more accurately covered, and the intercepting effect on the torpedo 1 is improved.
In summary, in the method for determining the suspension depth of the suspended type interception bomb, based on the estimation of the navigation depth at the tail end of the torpedo 1, other navigation characteristic factors such as the initial climbing distance and the climbing angle of the torpedo 1 are further analyzed, and the main factors such as the physical characteristics of the surface ship 2 platform, the damage characteristics of the interception bomb and the like are comprehensively analyzed, so that a reasonable suspension depth calculation method is formed, the suspension depth of the interception bomb in the underwater defense operation process is guided and determined, the suspension depth of the suspended type interception bomb 3 is more accurate and more effective to cover the navigation depth of the incoming torpedo 1, the interception effect of the incoming torpedo 1 is improved, the operation research of the suspended type interception bomb 3 and the analysis and evaluation of the system operation efficiency are supported, the accuracy and the effectiveness of the suspension depth of the interception bomb deployment are improved, and the navigation depth of the incoming torpedo 1 is theoretically covered, and the research on the operation use and the operation efficiency analysis of the suspended intercepting bomb 3 is supported, and theoretical support is provided for the design and the capability evaluation of the surface ship 2 anti-torpedo 1 operation weapon system.
