Abstract :
An algorithm is developed to reconstruct the two-dimensional (2-D) image of the surface plane or section plane of an object from reflected signal data when a sensor moves along a straight-line path. It is considered as a tomographic imaging problem from arc projections. The principle of tomographic imaging is introduced and an imaging algorithm is derived. Computer simulation results are given. The imaging algorithm may be applied to radar imaging for a partial terrain area, and to reflection mode ultrasonic computerized tomography
