Abstract:
     The invention discloses a differential short base expander in the field of ground observation technology. It is free differential short base expander or fixed differential short base expander. The structure of free differential short base expander is that the two ends of the base 1 are the measuring ends B which are separately supported by the two hanging systems 2; two measuring ends B separately arrange sensors 3 and labeling devices 5; the two labeling devices 5 are separately fixed on two second base b; the two sensors 3 are separately connected with the two front amplifiers 4; the two labeling devices 5 and the two front amplifiers 4 are separately connected with a recoding and controller 5; the measuring result is the measuring sum-of-products of the two measuring ends B.
