Research Of Ground Motion Metal Target Detection And Recognition Technology Based On Millimeter-Wave

With the rapid development of millimeter-wave technology, millimeter wave detection technology has become an important means of modern warfare to metal ground moving target acquisition information, the use of millimeter wave radiometer and target recognition algorithm can effectively achieve the objectives of the ground motion of metal detection and identification.At first, the paper mainly dissertate theory and methods of detection and recognition of millimeter technology to ground motion metal target. Having established a detection model is to ground motion target metal by millimeter wave radiometer. It is to determine whether the metal target is present according to the theory of millimeter wave radiation characteristics differences of the different substances. Having detected the goal, is classified and distinguish according to Johnson sentenced. Drawing a conclusion that signal has output at the rendezvous moments when the antenna beam met with a metal target and the effective range of important parameters for radiometers and missile though simulate the detection models.Secondly, in order to be able to accurately strike enemy targets, then using wavelet de-noising method to detect metal target signal for signal processing. The feature of signal is extract and to establish the target feature template. Fuzzy pattern recognition method is to identify the characteristic quantity of width, depth, and the energy to unknown target. And based on fractal feature recognition method is to identify which has been extracted characteristic quantity of energy. Recognition rates were respectively obtained to ground motion metal target of millimeter wave radiation.Then, through analysis of the false ground metal target detection information obtained radiation characteristics of a false metal target, which is characterized by a waveform can distinguish the true or false target. Meanwhile, the combination of several movement calculation shows that discussed the impact of the metal target direction of motion detection results to the detection system.Finally, the motion on the ground metal target of millimeter detection and recognition method, there are still problems in the analysis shows that, in order to further research in the future by working to improve the accuracy of the system parameters to achieve a variety of complex recognition algorithms to further improve the system overall performance, to achieve the goal of real-time precision strike.
