Short range imaging system based on a new microwave photonic multiplexing technique

Microwave imaging systems allowing the real-time scanning of short-range objects are difficult to implement on a large scale due to their complexity and cost. In this paper we introduce a new ultra-wideband multiple-input multiple-output radar using microwave photonic components in reception. These components permit ultra-fast time division multiplexing of all receiving signals and hence their measurement with a single acquisition channel. This architecture makes possible to decrease the time of acquisition compare to architecture with a sequential reception.
