Method on Submarine Attack Target Inside MinimumLaunch Range Circle of Sub-launched Torpedo

In order to attack the target which inside minimum launch range circle of sub-launchedtorpedo,in this paper,the calculate method of minimum launch range is built firstly,and the impactto torpedo shooting is analyzed;then this paper transforms the two-time rotating angle shooting modelswith various homing modes into a general equation according to the principle of solution encounter,and analyzing trajectory restriction for sub -launched torpedo. Based on this,material method oftorpedo shooting is studied under detection distance less of minimum launch range. Example resultdemonstrates the feasibility and validity of attack method lastly.
