Laser driven electron beam has important application value in the field of space radiation environment simulation. However, due to the shortcomings of poor spectrum tunability and high laser energy of the electron beam generated by laser direct irradiation of high-density solid targets, its wide application is limited. In this work, a scheme is proposed to simulate the orbital electron radiation in near-Earth space by using laser driven dual-plane composite target electron acceleration. It is found that the high-density solid target Ⅱ can provide a large number of low energy electrons, while the vertical plane target Ⅰ located in the front surface of target II can provide a small number of high energy electrons, which makes the electron energy spectrum very close to that of the space radiation environment. In order to evaluate the similarity between the generated energy spectrum and the space radiation spectrum, a method of evaluating the similarity of energy spectra is proposed, which can describe the local similarity and the global similarity of the energy spectra. For vertical plane target Ⅰ with low density, the electron acceleration is dominated by the laser ponderomotive acceleration that generates a half-wavelength oscillation. As the density increases, the electron acceleration gradually transitions from the laser ponderomotive acceleration to the surface ponderomotive acceleration, and the electron beam energy spectrum is modulated effectively. Meanwhile, the electron temperature of the generated electron beam is linearly related to the length and density of the target Ⅰ, and the optimal target parameters are obtained by the Bayesian optimization, and the generated electron beam is much better matched to the space radiation environment. Compared with the scheme of laser driven single-plane target electron acceleration, the proposed scheme has better tunability of energy spectrum and lower requirement of laser intensity. The results provide a theoretical reference for the experimental study of simulating space radiation environments in different orbitals by using laser-driven electron beams.
