Trajectory sag due to gravity and demodulation error caused by roll angle measurement error are the main factors that influence the guidance precision of Terminal Correction Mortar Projectile (following called TCMP for short) using pulse jets. TCMP dynamics model and guidance loop model are established, and then the impact of pulse jet impulse, pulse jet ignition waiting time and gravity on the guidance...
In this paper, by using the nature of Cyclotomic class, presents two new methods for constructing Different Set Pairs. The methods are based on the Cyclotomic class, and different Cyclotomic class could construct Different Set Pairs of Different parameters. New tools for using Different Set Pairs to construct Perfect discrete signal are provided.
