Study on Quantitative Efficiency Evaluation for Deception Jamming to ISAR
With study on deception jamming to ISAR greatly advance,the efficiency evaluation of deceptive targets is getting more importance.Combined with mechanism of ISAR imaging as well as composite image jamming technique of deceptive target,the paper proposes an approach to evaluate the efficiency of positive deception jamming quantitatively,which is based on the idea of evaluation of image quality of deceptive targets.General mean square error (MSE) of image quality,peak value offset (PVO) of image and correspondency degree index (CDI) of image are defined as evaluating indexes,and they are simulated when caused by aiming error,jamming bandwidth,jamming pulse duration error and PRF error.Quantitative evaluation for efficiency of jamming is realized and thresholds of the indexes are determined to fulfill effective jamming.Simulation result verifies the practicability,feasibility and validity of the evaluation method,which provides new indexes and technical approach for precise evaluation and comparison of effect of deception jamming to ISAR.
