Embodiment Construction
[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0017] combine Figure 1~5 , in the passive target positioning system (taking two-station plane positioning as an example), in the passive cross-location system based on direction finding, the observation stations A(0,0) and B(L,0) measure the target T(X , the azimuth angle of Y) is and Measurement error and obbey normal distribution The coordinates of the target T are thus obtained and satisfy the distribution suppose where intersection angle
[0018] Assume that the observation stations A and B receive the signals transmitted by the target T as S A and S B , the amplitudes are a and b respectively, and the corresponding channel Gaussian noise n A and n B obbey normal distribution Since the channel from the target T to the observation station A and from the target T to the observation station B is a parallel Gaussian channel, the rec...
