Description

technical field

[0001] The invention belongs to the technical fields of target characteristic analysis, target detection and target recognition, and relates to a water drop measurement system in a space environment. Background technique

[0002] Environmental control and life support systems are essential systems for any manned spacecraft. It is a significant sign to distinguish whether a spacecraft is a manned spacecraft, and it is one of the key technologies that must first be broken through in the development of aerospace technology from unmanned spaceflight to manned spaceflight. Among them, the environmental control system, commonly known as the air conditioning system, is a very important and quite complex system on the spacecraft. It is a system directly related to the health and life safety of astronauts, and it is also an important system related to the successful completion of space missions.

[0003] The basic task of the air conditioning system is to create a ba...
