Abstract
In this paper the systems of classic passive radar detection of radar targets are analyzed and the requests of superposition of two very close radar targets are defined. Also, there are analyzed reference methods of superposition based on the angle determination of incoming electromagnetic waves by waves sampling and determination of signal power spectrum as a function of space frequency in the presence of angular noise (clutter). By sampling a number of footprints of signals and by the estimation of the space frequency and the co variation matrix of received useful signals and noise, it is possible to repeat accurately necessary information about the resolution of two close targets at the sensor of the antiradar missile homing head. After comparing required and gained parameters: accuracy of direction standard deviation of direction, accuracy of separation of two sources and probability of reliable separation, it is recommended in the paper to use a modified method of maximum entropy, as the best method for the separation of two angular very close targets that are seen by the homing head of the antiradar missile.
