FIGURE 1-9b Time histories of the torpedo rudder deflection, the error phi-psi, the angle phi and the squared distance dd to the target (see text)
The target angle psi is the angle between the horizontal line in Figure 1-9a and a line joining the torpedo and target The target coordinates xt, yt, the squared distance-to-target dd, and the target angle psi are given by
xt = xt0 + vxt * t yt = yt0 + vyt * t psi = arctan((yt y)/(xt x)) dd = (x xt)2 + (y yt)2
We aim the torpedo at the target by making the initial value of phi equal to psi The initial values of u and v are set to 0 We control the rudder to keep the torpedo turned toward the target Such simple pursuit guidance works only for low target speeds unless initially one is
