中文说明：步进频率雷达的距离方程MATLAB程序，参考一篇文献编写的，可以根据不同的探测距离来计算出所需要的脉冲宽度。其中大气损耗部分参照的是相关国军标。使用时，可以直接将大气损耗设定为每公里损耗值。供参考，含文献。
English Description：
The matlab program of range equation of stepped frequency radar, which is written with reference to a document, can calculate the required pulse width according to different detection range. The atmospheric loss part refers to the relevant national military standards. When in use, the atmospheric loss can be directly set as the loss value per kilometer. For reference, including literature.
