Simulation And Research Of Frequency Hopping Radio In The Complex Electromagnetic Environment

Abstract:At present,most of military shooting trainings are still using traditional manual target-scoring systems,which have some defects in security and efficiency.Automatic target-scoring system is fast,efficient and precise.It has advantages compared with the manual method.Therefore,the research on automatic target-scoring system for shooting will make great progress in the modernization of training for the army.Based on armed and practical training,this paper presents a lot of careful analysis and study on automatic target-scoring system.An automatic target-reporting system is designed and related image processing algorithms are studied in this thesis.A large number of simulation experiments are conducted.The main work of this paper is as follows:1. Background and status of current study on automatic target-scoring systems are described.2. An automatic target-scoring system based on image processing technologies is proposed.Hardware platform and software implementations are designed.3. Images of the target are captured,and then sub-sampled using wavelet transform.Furthermore,median filter,geometric correction,image subtraction and binarization algorithms are used to process the images.Especially,an improved two-dimensional Otsu algorithm is put forward.4. Morphological filtering,Canny edge detection are used to get clear edges of bullet-spot.Then Hough Method is presented to find the core coordinate.5. According to the geometric relationship between the core point of the bullet. Hole and the loop lines,the corresponding shooting score is calculated.Large amounts of simulating show that our automatic target-scoring system is efficient and precise.lt can be settled for the military training.
