An analytic target model is adopted to investigate the image reconstruction properties with Received in revised form limited relative angle range, which are useful to verify the target shape from the incomplete image, 17 September 2015 analyze the shadowing effect of the target and design the satellite payloads against recognition via re- Accepted 20 September 2015 flective tomography approach. We proposed an iterative maximum likelihood method basing on Baye- sian theory, which can effectively compress the pulse width and greatly improve the image resolution of Keywords: incoherent LRT system without loss
