tracked using the JTC of Fig. 7.6, if the duty cycle of the JTC is 0.05 sec.
7.27 Refer to the role of the correlation peak position as a function of target
motion in Fig. 7.63.
(a) Determine the aspect ratio of the image array.
(b) Assuming that the target is revolving in a circular path and the
system is set to run autonomously, calculate the tracking errors after
five revolutions.
7.28 Refer to Sec. 7.4, and consider the dynamic state of the target at the kth
frame as given by

x(k)

The velocity and the acceleration of the target can be handled by the JTC
system of Fig. 7.6. Describe a Kalman filtering procedure so that
multitarget tracking can be performed by the proposed hybrid-optical
JTC.
