Aiming at the problem that infrared detectors can only measure the surface radiation of a target while flying in space. And it is difficult to obtain the hollow scale of the target. This paper designs a method for inverting the hollow scale based on the dynamic change of radiation energy. Taking a hollow sphere as an example, the relationship between the target radiation intensity and the hollow scale and time is given. Analyzed the relationship between the target radiation amount its influencing factors. On this basis, the ralationship feature between radiation and hollow scale under different time conditions is given. Through the method in this paper, hollow scale of the target can be estimated to support target detection and recognition analysis.
Aiming at the problem of noise and the difficulty of periodic extraction in infrared data acquisition. In this paper, a line method of infrared data period extraction based on CEEMDAN is proposed, which can eliminate the noise and interference of infrared data and accurately extract the period. The method preprocesses the original foreign teacher data by determining the signal mode, so as to improve the quality of infrared data; However, the data cycle was accurately extracted by using the method of correlation split mean cap. Finally, the validity and correctness of the extraction method are verified by simulation experiments.
