Description
Technical Field
The invention belongs to the field of space debris detection, and particularly relates to a highly integrated visible light waveband space debris detection system which has the characteristics of modularization, integration, simple input/output interface, high positioning precision and the like, can realize image acquisition and processing, can position all targets on an image astronomically, can be arranged on a new tracking rotary table, can also be arranged on an existing tracking rotary table, and is a space debris detection system with high integration and modularization degree and high cost performance.
Background
In many fields such as scientific research, military affairs and the like, the space debris needs to be monitored, so that the position and the change of the space debris in the sky at each moment are given, the operation orbit of the space debris is determined, the accurate information of the space debris is obtained, and the safety of the in-orbit spacecraft is guaranteed.
The invention of CCD replaces the traditional photographic observation and becomes one of the effective means for monitoring the space debris. Due to the increase of human aerospace activities, space debris in space is more and more, the space debris larger than 1 cm reaches tens of thousands, even hundreds of thousands and hundreds of thousands in the future, and the safety of the in-orbit working spacecraft is threatened. In order to obtain information about these space debris, it must be observed.
At present, two modes of angle measurement and distance measurement are mainly used for the accurate measurement of passive space debris. The angular observation of the space target is to use the optical subsystem of the optical telescope to collect the sunlight reflected by the space target, the detector subsystem to convert the photons into electrons and digital images, and the image processing subsystem to complete the image processing, the detection and the positioning of the moving target, thereby completing the precise angle measurement of the space target in the visible light band.
For passive space debris ranging measurement, two modes of laser ranging and radar ranging are available. The working principle of laser ranging is that laser is emitted to space through an emission subsystem of an optical telescope, a part of light of the laser beam after encountering space debris is reflected to a receiving subsystem of the optical telescope, and when the number of received photons reaches a certain threshold, the detection of the space debris is completed. And calculating the round trip time of laser emission and laser reception to obtain the distance between the optical telescope and the space debris. The radar ranging has the working principle that electromagnetic wave signals sent to a space have part of energy received by a radar receiver after encountering space debris, and when the transmitted echo signals exceed a certain threshold voltage value, the radar receiver completes the detection of the space debris. And calculating the round trip time of the transmitted wave and the reflected wave to obtain the distance between the radar and the space debris. The radar ranging and the laser ranging are active detection, are not influenced by weather and day light and are all-weather and all-day detection equipment; the latter is affected by weather and daylight and is not an all-weather detection device.
The traditional space debris optical detection system has the following characteristics:
1. the space debris detection system consists of an optical system, a detector and an image acquisition and processing part, and is independent of each other;
2. the detector does not have the function of accurate timing, and is only responsible for converting photons collected by the optical system into electrons and converting the electrons into digital images;
3. the image acquisition and processing control detector acquires an image and receives the image; receiving time data (provided by a time system) and code disc data (provided by a servo system) of an external input fixed frequency (such as 20Hz, 50Hz or 100 Hz); obtaining time and code disc data corresponding to the exposure center moment through interpolation; or receiving the time and code disc data which are sent by a latch (receiving the code disc data of the time data machine with fixed frequency, the exposure square wave signal output by the detector and the time and code disc data corresponding to the exposure center time and are consistent with the image sampling frequency and the exposure center time);
4. the coupling among the components is high, and the independence is weak;
5. the length of a data transmission line between the detector and the image acquisition and processing is limited, or the structure needs to be prolonged;
6. the image acquisition and processing is usually an industrial control computer, is bulky, has requirements on the ambient temperature, and is usually installed in a cabinet of a room.
Therefore, the traditional optical detection system can not meet the development requirement of space debris cataloging, a highly integrated visible light waveband space debris detection system is provided on the basis of the background, the system realizes accurate latching of image exposure center time and code disc data through integration of a detector, image acquisition and moving target detection and positioning, and solves the problems of time and image asynchronism caused by different processing programs of latching of the image exposure center time and image acquisition of the traditional visible light detection system, frame error caused by close exposure time and image acquisition period caused by real-time performance of an operating system and inconsistency caused by data interaction between different programs. The device receives a second signal and a second data packet which are input from the outside and a code disc data packet with fixed frequency through a serial port, and realizes data exchange with the outside through a network port. The system has simple input and output (1 DC power supply, two serial ports and 1 network port), and is a space debris detection system with high integration degree, high safety, high positioning precision and high cost performance. The system for detecting the space debris in the visible light wave band with the medium caliber can be arranged in areas with good weather and day light conditions, high altitude, large temperature difference, poor matching conditions and poor living conditions. The long-focus and short-focus double-focus medium-caliber visible light band space debris detection system can be used for night observation and daytime observation, and is a full-time space target detection system.
