摘要	In order to deeply study the feasibility GEO imaging techniques, this paper deeply analyzes and compares three techniques for active interferometric synthetic aperture imaging by means of sensitivity. These techniques are Fourier telescopy, imaging correlography and sheared-beam imaging. Using a SNR(signal to noise ratio) model for photomultiplier tubes and laser range equations, this paper gives a detailed analysis of the limit detection capability of each technique when SNR is 5. Through simulation, it was found that the lowest single pulse energies for Fourier telescopy, imaging correlography and sheared-beam imaging were 11.4 J, 0.73 MJ and 3.1 MJ, respectively. The conclusion is that Fourier telescopy is the best among these three imaging techniques, making it most suitable for GEO imaging in the present era. 2019, China Science Publishing & Media LTD.
