Ballistic Target PHD Filter Based on Infrared Focal Plane Ambiguous Observation

Abstract: Space-based early warning system, the main detection means of which is passive detection based on focal plane, is an important part of ballistic missile defense system. The focal plane is mainly composed of CCD, and its size can reach the micron level, so the pixel is often regarded as point of no area in image postprocessing. The design of traditional tracking methods is based on this, and the observation based on the focal plane is modeled as the azimuth with random noise. However, this modeling is inaccurat… Show more

“…Space-based infrared cameras (SBIRCs) are commonly used for target tracking in the boost stage. [1][2][3][4][5] SBIRCs combine the advantages of space-based platform and optical sensor, passively recording target thermal radiation data to locate targets, which makes them more defensible. 6) A commonly employed strategy is to represent the statistical properties of the noise of infrared cameras (IR) by Gaussian distributions, 7) or mixture Gaussian distributions.…”

“…In this paper, the measurement model of the sensor is reconstructed. Considering that the measurement is inaccurate and cannot be described using random noise, it should be modeled as an UGA (unambiguously generated ambiguous measurement) [ 9 ]. Different from the traditional measurement method, the ambiguous measurement is not a specific value containing random noise, but the approximate area where the target is located.…”
