The manufacturer can commission the power of phone jammer

There are two main laser radar ranging of 1.3 Laser radar ranging phase ranging and pulse ranging phase ranging principle is by measuring the laser is modulated from the launch phase changes in the receiving interval, calculated by a phase change of the measured distance, ie, c R = φ 4π fc light airborne speed; f is the modulation frequency, △ φ is the phase modulation cycle, measuring the distance is not only related with the phase integer cycle measured when measuring the distance required for more than an integer cycle , it is difficult to determine the true distance. The power of cell phone jammer has been determined to some extent.
So in this way is mainly used in close measurements, such as robot vision, and automatic car navigation and other fields ranging radar pulse from the transmitter to the receiver through the counter measuring laser pulse number, through an over pulse the number of distance if the time scale oscillator frequency f, in the back and forth between the laser radar and the target time t (ie the time interval between the sampling signal and the echo signal) contains a number of standard pulse is n, then be measured distance L = cn / (2f) in the range of ranging capability, ranging pulse can be measured far enough goal, aircraft navigation and missile guidance pulse ranging LIDAR laser scanning technology at home and abroad Research. The manufacturer can commission the power of phone jammer .
Laser scanning technology Research in the national "863" program has supported the research of laser scanning technology, "308" theme of the project research is mainly focused on the airborne laser image mapping system design, manufacturing and data processing. Access to information subsystem Airborne Laser Ranging - scanning imaging mapping system set-ray machines scan imaging techniques, laser ranging technology, GPS navigation and positioning technology, attitude measurement technology is one hardware synchronization and strict matching, the use of distance of the scanned image and DEM information for feature classification and identification with the image information. The system consists of five sensors, working band covers the entire series of visible light, infrared and microwave platform with a high school low-altitude aircraft distributed system for application-oriented objectives.
