Comprehensive geolocation performance analysis of NRCS based on probability theory

HAN Guo-xi,HE Jun,QI Jian-qing(Dept.of Command,Electronic Engineering Inst.,Hefei 230037,China)  
The probability density of every location point was given according to the TDOA and the location of emitter and receiver,and then the peak value of the total probability density function in the whole detection region was obtained to serve as the geolocation result.Therefore,one-order linear equations will be solved without the need for solving high-order nonlinear equations.The operation speed was accelerated due to avoiding complex matrix calculation.Meanwhile,the geolocation performance of NRCS under the different working mode was analyzed in detail.The theoretical analysis and simulation results show that the geolocation performance of the integration working mode is much better than that of the passive and active working modes.
