The synthesis of sequential detection algorithm trajectories with adaptive changes in the primary detection threshold on the basis of maximum information down factor with the use of two-threshold Wald test. To detect the likelihood ratio is used, taking into account different hypotheses about the origin of marks in the tracking gate and the mark, did not exceed the detection threshold. By simulation shows that the proposed algorithm ensures threshold gain in signal / noise ratio of about 4 dB compared with the case of target detection for one pulse packet.
