Abstract

Combination of deep space laser communication and ranging is nowadays well-appreciated. For purpose of improving the communication and ranging performance, this paper proposes direct sequence spread spectrum (DSSS) assisted high receiving sensitivity inter-satellite integrated laser communication/ranging link. A thorough analysis for our proposed system is carried out, including optical receiving model, laser communication and ranging model, and theoretical performance analysis. DSSS performance in laser communication and ranging system is first researched by not only simulations but experimental results. Experimental, Monte Carlo, and theoretical results agree with each other. These results show that over inter-satellite link, on one hand, DSSS technique is an effective method of improving the receiving sensitivity of laser communication. On the other hand, DSSS effectively increases the distance and the precision of laser ranging.
