| Abstract: | The operation frequency band of microwave radiometer on SZ-4 spaceship is located up to millimeter wave, This is hither to unprecedented in development of our spacecraft antennas. By means of computer aided integrated method for mechanical, electrical and thermal design, beginning with choice of materials the optimal design on electro-and structure has been combined with manufacture and assembly technology effectively to guarantee the minimum deformation of the reflector. This paper describes controlling and realization of high accuracy of reflector shape. |
