Sentinel 1文件名命名规则如下图:

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RAW、SLC、GRD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。
alibaba/Sentinel: Sentinel 是阿里巴巴开源的一款面向分布式服务架构的流量控制、熔断降级组件,提供实时监控、限流、降级和系统保护功能,适用于微服务治理场景。

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

* 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
