Based on the logarithmic FM biomimicry wave signal of military radar ranging method analysis

Research the military radar ranging bionic accurate waveform design and optimization, in order to strengthen the number of bionic FM signal delay resolution. Biomimicry in traditional military radar wave signal distance measurement method on the basis of introducing the logarithmic frequency modulation of the bionic wave distance measuring process was optimized, and the process of the bionic model are given, especially in the process of filtering filter group, using a set of Q value of the same logarithmic frequency modulation signal, the bandwidth is Lyons FIR linear filter group implementation of Cochlear model change. The simulation results show that in the military radar ranging, by using this method to treat the received echo signal analysis and from the aspects of target detection curve, distance estimation compared with the matched filtering method, the accuracy is higher, more stable performance.
