Sentinel 1文件名命名规则如下图:

https://i-blog.csdnimg.cn/blog_migrate/c0782265f015ac820153b08ca4617c47.jpeg

官网的详细说明:

https://sentinel.esa.int/web/sentinel/user-guides/sentinel-1-sar/naming-conventions

以下为例子:

S1A_EW_GRDM_1SDH_20180112T082556_20180112T082700_020119_0224E3_7F9B

S1A是卫星Sentinel1-A的标识

EW为模式名称,有SM、IW、EW和WV。

GRDM为产品名称以及分辨率,产品有RAWSLCGRD或者OCN,分辨率类型为 F (Full resolution)H (High resolution)M (Medium resolution)

1SDH,1为处理级别,可以为0、1、2。S为产品类型是Standard (S) 或者是Annotation (A),DH是极化方式,如下:

SH (single HH polarisation)

SV (single VV polarisation)

DH (dual HH+HV polarisation)

DV (dual VV+VH polarisation)

20180112T082556_20180112T082700是产品的开始和结束的事件,其中T是日期和时间的分隔符。

020119是绝对轨道号,绝对轨道数考虑的是发射后第一个上升节点穿越后的轨道。相对轨道数是从1到一个重复周期中包含的轨道数的计数。

S1-A的相对轨道号计算公式为:

The Relative Orbit Number = mod (Absolute Orbit Number orbit - 73, 175) + 1

S1-B的相对轨道号计算公式为:

The Relative Orbit Number = mod (Absolute Orbit Number orbit - 27, 175) + 1

0224E3是任务数据利用标识符(mission data-take identifier)

7F9B是产品唯一识别码,使用CRC-CCITT在清单文件上计算CRC-16生成的十六进制字符串。

Fix the issue in the spring-webmvc-v6x-adapter where, after configuring http-method-specify:true, the prefixes for different request methods were not concatenated. Fix incorrect time unit in the tooltip when adding a new circuit breaker rule with statistical window duration. * Fix the bugs mentioned in issue #3562 and #3563. Fix the issue in the spring-webmvc-v6x-adapter where, after configuring http-method-specify:true, the prefixes for different request methods were not concatenated. Fix incorrect time unit in the tooltip when adding a new circuit breaker rule with statistical window duration. * Fixed the issue where the original test class was affected by the concatenation of resource names after adding the logic for the HTTP prefix concatenation. * remove mseHttpMethodSpecify field and update the unit test as suggested. * retrigger CI 24 天前
e60f0d0e * Simple rules should have higher priority than regular expression rules * Add optional switch to skip regex matching when simple rules already match, default: false, keeps backward compatibility. * fix RuleManagerTest unit test failure 24 天前
