Abstract

The PN guidance model was established with the three error sources, heading error, angular noise and glint effect. Base on the method of adjoint and non-dimensional method, the adjoint model of the PN-guidance was obtained and the expression of non-dimensional miss distance was deduced. It is concluded that the induced miss distance has a close correlation with navigation constant N, system damp and bandwidth while a low system damp and bandwidth has adverse influence on miss distance. The induced miss distance does not decrease to zero but increase to a constant value with the increasing flight time of the engagement when angular noise and target glint was introduced in the system.

Key words： heading error; angular noise; target glint; method of adjoint; proportional navigation; miss distance
