Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.
A sample product,
The introduction of product above is a system based on FM radio band.We also have products based GPS/StarLink,VHF/UHF,DBS-T and other radio systems. Which system applies to you best is chosen according to local radio environment and your requirement of specifications. Example specification follows,
| Item | Parameter |
| Detection Range | ∽60Km |
| Radar Cross Section | 0.01sm∽ |
| Detection Time | 1.2s |
| Truth Probability | 96%∽ |
| Concurrent Track | ∽5 |
| Precision | 2m∽ |
| Response Time | 2s |
Application:
Detect invasion of drones. This can be used for guard of key spots,such as power plant,mansion,buildings,dams,etc.
Guarding the boats and ships offshore.Passive radar based on the bank can track the boats and ships.If some danger occurs, the track is disrupted.So a warning will be sent.The postions of boats and ships can be also be tracked.
Detecting stealthy aircraft. Passive radar has a much larger radar cross section,due to its bistatic intrinsical property.
Watching meteor. It can also be used to watch other phenomena of astronomy.
Monitoring debris of LEO&MEO orbits. Large amount of debris are in low earth orbits and middle earth orbits.With illumination of GEO(Geostationary Earth Orbit) satellites,passive radar can detect these debris.
No license of radio is required. Passive radar uses existed illumination,eg. civil FM broadcast and TV broadcast. It radiates no radio signal,so no license required by authority.
Covert. Because of no radiation of radio and using with civil illuminator, passive radar can not be detected by anyone easily.It silently works.
High mobility. Passive radar needs much less power than active radar(traditional radar). It also has a simple and small structure.So it is mobile.
Low price. Price can be cut down to thousand dollars comparing with million dollars of traditional radar.
Little power is needed. With average power of about 160 watt, it is low cost in use.
Components:
Two antennas;
One signal processing host;
One power adapter;
Coaxial cables and attachments.
