The paper presents a new approach to the secondary processing of radar information in multi-position passive complexes. The proposed approach is based on the use of maximum likelihood estimates of discrete measurement counts at finite time intervals, taking into account the motion of the radio emission source. The advantage of the proposed approach is the possibility to work on non-full measurements. The disadvantage is the delay in the output of the solution, as well as a decrease in the rate of output of the solution. The article presents an analysis of the effectiveness of the proposed approach, as well as the results of testing the developed algorithm on real measurements.
