A Phase History Modeling Method for High Resolution Spaceborne SAR;

Research on the spaceborne SAR countermeasures;

The suppression jamming effect on spaceborne and airborne SAR is calculated and analyzed by simulation.

Satellite borne laser warning and area target laser warning networking technology;

Study on background radiation characteristic of satellite borne laser warning system

Satellite is facing more laser threatens, it is the tendency to research satellite borne laser warning technique.

Compression Technique for onboard CCD Image of Space Solar Telescope;

There is much higher fault ratio to onboard system than other computer systems working on ground because of its bad working environment.

A dynamic alignment design scheme for a space-borne Fourier transform spectrometer is provided.

The effect of space flight on seed is weakened when the seed moisture content approaching 10%～12%,reversely the effect is strengthene.

were treated by space flight,and young tender leaves of the germinated plants were used as explants for callus induction,testing the effects of different exogenous hormones on the tissue culture.

Seeds of Brassica juncea var gemminfera were treated by space flight,and contents of chlorophyll and soluble carbohydrate in leaves of the germinated plants were tested.
