本文提出了一种利用直接解调法提高编码掩模望远镜角分辨率的新方法。DDM已被应用于INTEGRAL/IBIS的真实的和模拟数据。IBIS/ISGRI的角分辨率已从约13'提高到2'。
We develop a new procedure to improve the angular resolution of coded-mask telescopes by the Direct Demodulation Method (DDM). DDM has been applied to both real and simulated data of INTEGRAL/IBIS. The angular resolution of IBIS/ISGRI has been improved from about 13' to 2'.
