【Abstract】 This paper firstly introduces the mathematical model of stepped frequency and MMW one dimensional range imaging technique.Secondly,the mathematical model of one dimensional range imaging for high range resolution MMW seeker when there is relative motion between the missile and the target is given.Using this mathematical model,the influence of missile-target relative motion on one dimensional range imaging is investigated by computer simulation.Finally,the value of the compensating error of this relative motion between the missile and the target is derived when one dimensional range imaging technique is used for target identification.更多还原
