%X <p>The Doppler character of low-earth orbit satellites, carrying multi-beam receiving antenna, is different from the character of single-beam antenna systems. In order to analyze the Doppler character of each beam, expression of iso-Doppler characteristic curve was derived with help of establishment of vector analysis model. The characteristic curve picture was obtained using computer simulation. Analysis of each receiving multi-beam Doppler character was achieved when combined with the multi-beam coverage calculation. Finally, the preliminary application on the on-board multi-beam captures module was explained and illustrated.</p>
