Abstract :
The difference of the image generated by real target and digital-image-synthesiser (DIS) is analyzed. Then two methods are deduced to recognize deceivable jamming generated by DIS. One is the uncontinuity of the false target in Doppler section which is caused by the quantization of phase increment. The other is the target number and pose in the imaging field after ISAR processing when the pulse repetition frequency (PRF) of the DIS mismatches with the opposed radarpsilas PRF. With the two methods, the limitations of DIS deceivable jamming are found, and the false target generated by DIS is effectively recognized according simulation.
