摘要
A multifunction millimeter-wave system (10) that provides simultaneous and prioritized active radar protection and surveillance, high digital data rate communications, interceptor missile guidance, passive surveillance and IFF interrogation for a military vehicle. The system (10) includes a multi-function control computer (14) that provides high level control functions. The system (10) also includes a plurality of azimuth sector sub-systems (12), each including a steerable antenna (26) that directs a millimeter-wave beam to a particular location within the area covered by the sector sub-system (12). Each sector sub-system (12) also includes an FPGA-based modem (20) that performs digital signal processing for the various system operations, such as signal modulation and demodulation. Each sector sub-system (12) also includes an IF/RF transceiver (22), including a direct digital synthesizer (24), for providing signal tuning and frequency up-conversion and down-conversion.
