ZJSC-LD12 two-in-one radar audio and video life detector

1. Product introduction:
The radar life detector is a high-tech professional rescue equipment designed for disaster rescue sites such as earthquakes, avalanches, and building collapses. It is mainly based on the time-domain Doppler echo generated by the human body motion on the radar signal to analyze and judge the existence of life bodies in the ruins and the specific location information of the life bodies. At the same time, it uses ultra-wideband electromagnetic pulse signals to penetrate the ruins. Combining with professional radar signal processing algorithms, based on the time-domain Doppler effect generated by weak movements such as human body movement, breathing, heartbeat, body shaking, limb swinging, etc., on the radar echo, it can analyze and judge whether there is a closed area or an invisible area. There is no living organism and its specific location information is calculated through an algorithm, and the test information is displayed on the handheld terminal device. Finally, the function of quickly detecting and searching for survivors in the ruins is realized, helping rescuers to improve rescue efficiency.

The whole device is composed of a radar host and a handheld PDA; it is small in size, light in weight, no probes and cables are required, easy to arrange and operate, accurate in positioning, and meet the requirements of harsh rescue environments.
 
2. Basic functions:

1. Non-contact detection function: The detector can detect characteristic signals such as breathing or heartbeat of living bodies without digging ruins, digging holes and piercing holes, and without touching living bodies.
2. Wireless control function: The control terminal has the function of controlling the radar host, including: host initialization, start detection, stop and close.
3. Scanning and display function: The detector has the ability to accurately scan the entire detection distance range, and display the detected human movement and breathing results on the screen in different graphics.
4. Automatic judgment function: Automatically judge whether there is a living body through an intelligent algorithm.
5. Data transmission function: wireless data transmission and built-in network port data transmission function.
