Abstract:
The continuing growth of the orbital debris population is now recognized world-wide as an environmental issue which must be better defined and addressed now to preserve near-Earth space for future generation. The distribution of the space debris in the LEO and the threaten of debris to the spacecrafts are introduced. Over the last decades, a number of technologies have been developed by the scientists for detection and measurement of the physical, chemical, and dynamical characteristics of dust and debris including (1) impact-plasma detection utilizing thick and ultra-thin targets; (2) charge induction in wires; (3) impact-induced discharge in a Metal-Oxide-Silicon (MOS) capacitor. In this report, A new methods was introduced, which employed a Polarized PolyVinyliDene Fluoride (PVDF) polymer film and fast electronic pulse techniques. The detector is intended to provide direct observations of space debris and interplanetary dust in the space, returning time resolved impact data, with approximate mass and velocity information. The advantages of ruggedness, no bias requirement, ease of large area sensor construction, and space reliability inherent in the PVDF dust sensors are well suited for a variety of dust and debris studies in space. The output of the fast electronic pulse techniques are used to analyze the mass of debris. Two sensors are placed in a Time-Of-Flight (TOF) telescope, which is used to measure the speed of the debris.
