Individual imaging system (microwave)
Individual soldier image system (microwave) adopts coded orthogonal frequency division multiplexing modulation / demodulation technology. It has the characteristics of narrow transmission band (2 / 2.5 / 4 / 8MHz) and strong anti-multipath interference ability, which can realize non-visual Distance (NLOS), real-time transmission of high-quality images under high-speed motion.
The system adopts H.264 / MPEG-2 audio and video compression standards, and the resolution reaches DVD resolution (720 * 576 @ PAL /
720 * 480 @ NTSC), the image is clear and smooth.
Can be applied to fire protection, civil air defense emergency, urban management law enforcement, environmental protection monitoring, three defense emergency response, water conservancy flood prevention, power rescue, railway rescue, maritime law enforcement, maritime surveillance inspection, customs border control, terminal monitoring, forest fire prevention, oil field theft prevention, military surveillance, television Broadcast, etc.
Can be used as an individual launch-command monitoring vehicle or an individual launch-command monitoring center and other applications.

突发事件应急通信方案： l Emergency communication plan:
For terrorist incidents, natural disasters, major and sudden epidemics, nuclear leakage accidents, environmental pollution, mines, oil and gas fields, and other emergencies, the rapid implementation of the following programs can enable command centers and leaders at all levels to speed Understand the situation on the spot, start the emergency plan in time, realize rapid response, implement emergency rescue and rapid disposal and other measures, monitor the whole process of the incident and issue instructions in a timely manner.
The front-end personnel carry individual soldier equipment to collect audio and video signals and transmit them to the mobile relay vehicle. After receiving the combined acquisition information on the vehicle, they connect to the vehicle-mounted (relay) equipment. The relay relay launches, forming an emergency communication link with a distance of about 30 kilometers to the command center.
城市应急指挥通信系统覆盖方案 l Urban emergency command and communication system coverage plan
The front-end on-site collection vehicle is installed with high-power on-board equipment to patrol in various areas of the city, and the collected audio and video information is transmitted to the nearest receiving point in real time, and the receiving point is transmitted to the command center using microwave, optical fiber or special network facilities.
