| Abstract: |
| SIGINT（Signal Intelligence） satellite is used to detect, intercept a
nd locate electromagnetic(EM) signals radiated by systems such as ground radar,
communication and TT&C systems. It is an important means for space reconnaissanc
e. The missions and classification of SIGINT satellites are introduced. The comp
onents, main specifications and features are analysed. The key signal intercepti
on and receiving technology is discussed, including large antenna and its deploy
ment technology, integrated channel with wideband, high sensitivity and large dy
namic range, onboard signal processing technology and space environment adaptabi
lity,etc. Finally the development trend is expected. |
| Key words: space reconnaissance SIGINT satellite signal processing receiving space environment adaptability |
