Abstract
The aim of the study is imaging of moving objects, asteroids illuminated by continuous coherent wideband signals illuminated by pulsars. As pulsars are placed on hundreds of light years from the Earth, objects crossing pulsars’ emission beams are considered as second sources of electromagnetic waves, carrying object’s shape and velocity information that ca be extracted by application pulsar emission-based inverse aperture synthesis. Inverse synthetic aperture radar (ISAR) scenario, geometry and kinematics are analytically described. Models of pulsar signals and ISAR signals secondary emitted by asteroids are suggested White Gaussian noise of high level is added to the ISAR signal in order to approach scenario to reality. Two-dimensional fast Fourier transform for image extraction is applied To verify mathematical model and imaging algorithms numerical experiments are carried out.
