In the first step, the general torpedo 1 starts climbing when it finds a target and starts an attack. The climbing aiming point may be different due to the difference in guidance type of the incoming torpedo 1, and is simplified here to the position of the present surface vessel 2.

In the third step, when the upper boundary of the vertical boundary of the array of the suspended intercepting bomb 3 is the upper boundary of the intercepting range, the maximum deployment suspension depth of the suspended intercepting bomb 3 is calculated:
When L is less than or equal to D1, namely when the torpedo 1 starts to climb, the horizontal distance between the torpedo 1 and the water surface ship 2 is not less than the deployment distance of the suspended intercepting bomb 3; the depth of the torpedo 1 is continuously reduced along with climbing, namely, H3/H2=L/D1, and the maximum deployment suspension depth of the suspension type interception bomb 3 is as follows:
h=h1+l/d1×h2+r, or h=h1+l×tan θ+r, where L is the horizontal distance from the water surface vessel 2 at the position where the array of suspended interceptors 3 is deployed, and D1 is the horizontal distance from the water surface vessel 2 when the torpedo 1 starts to climb; h3 is the difference between the depth of the upper boundary of the suspended intercepting bomb 3 and the depth of the bottom of the water surface ship 2 when the upper boundary of the suspended intercepting bomb 3 is consistent with the upper boundary of the intercepting range; h2 is the depth difference between the depth at which the torpedo 1 sails before climbing and the depth at the bottom of the surface vessel 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; θ is the climbing angle when the torpedo 1 transitions to the climbing stage;

In the third step, the deployment distance of the suspended interception bomb 3 is the horizontal distance between the position where the suspended interception bomb 3 falls and the position of 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 arrangement suspension depth of the interception bomb, theoretically cover the navigation depth of the attack torpedo 1, support the operational use and operational efficiency analysis and research of the suspension interception bomb 3, and provide support for the design and capability assessment of the anti-torpedo 1 operational weapon system of the water surface ship 2.
The method considers main factors such as the voyage characteristics of the tail end of the voyage of the incoming torpedo 1, the physical characteristics of the water surface ship 2, the damage characteristics of the suspended interception bomb 3 and the like, and calculates the laying depth of the suspended interception bomb 3 according to the relative position relation.
The following will specifically describe this method by taking the calculation of the suspension depth of the small-caliber suspension type interceptor spring 3 as an example:
(1) Parameter setting:
The navigation depth before climbing of the incoming torpedo 1 is about 60m; the climbing angle of the incoming torpedo 1 is about 1.5 degrees; the draft of the surface vessel 2 is about 6m; the furthest array distance of the small-caliber suspension type interception bomb 3 is about 1200m; the damage radius of the small-caliber suspension type interception bomb 3 is about 14m;
(2) Calculating the minimum array depth of the suspended intercepting bomb 3:
The climbing angle of the torpedo 1 is generally smaller, the range of 1-2 degrees is more, and the value of D1 is larger than the value of L at the moment; therefore, the minimum suspension depth of the suspended interceptor bomb 3 can be calculated by applying the above formula to the above formula: h=23 m;
(3) Calculating the maximum array depth of the suspended intercepting bomb 3:
according to the above method, the maximum suspension depth of the suspended interceptor bomb 3 is calculated as follows: h=51m.
Therefore, under the condition of set parameters, the range of the array suspension depth of the suspended interceptor spring 3 is 23-51m.
Because the small-caliber suspended interception bomb 3 has smaller damage radius, in order to reduce the winding of two adjacent suspended interception bombs 3 under water caused by the suspension being too deep, the interception bomb array is difficult to ensure that all interception bombs are distributed at the far-range of the action range in the use process, and the minimum suspension depth of the suspended interception bomb 3 is properly reduced and is about 18m finally determined through analysis.
In the practical application process, the factors such as the length and the width of the platform can be considered in combination with the navigational speed, the heading and the azimuth relation of the water surface ship 2 and the incoming torpedo 1, the suspension depth of the suspension type interception bomb 3 can be properly adjusted, the navigational depth of the incoming torpedo 1 can be more accurately covered, and the interception effect on the torpedo 1 is improved.
In summary, in the method for determining the suspension depth of the suspension type interception bomb, on the basis of considering the estimation of the voyage depth at the tail end of the voyage of the torpedo 1, other voyage characteristic factors at the tail end of the voyage such as the initial climbing distance, the climbing angle and the like of the torpedo 1 are further analyzed, and meanwhile, the physical characteristics of the platform of the water surface ship 2, the damage characteristics of the interception bomb and other main factors 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 to be determined, the suspension depth of the suspension type interception bomb 3 is enabled to cover the voyage depth of the incoming torpedo 1 more accurately and effectively, the interception effect of the incoming torpedo 1 is improved, meanwhile, the operation research and the system operation efficiency of the suspension type interception bomb 3 are supported, the accuracy and the effectiveness of the voyage depth of the interception bomb are improved, the voyage depth of the suspension type interception bomb 3 is theoretically covered, and the analysis research of the anti-torpedo 1 of the ship 2 is supported, and theoretical support is provided for the evaluation of the weapon system design and capability of the anti-torpedo 1 operation of the ship.
