Abstract:
One of the essential problems of watching monopulse radar protection is impossibility to accompany the purpose at suppression unceasing by active noise hindrance (ASHP) with directions main petal diagrams to directivities (DN) of the antennas, when ways time or frequency breeding do not work because of continuity of the hindrance and big width of its spectrum.
The results of the basic researches and modeling show the possibility of the using the way of the measurement of the angular unbalances to account cone-shaped deployment.
The purpose of the work is a study to capacity to work of the way of the measurement angular unbalances to account of the cone-shaped deployment total DN on issue at suppression ASHP on main petal DN antennas sector (quadrant) MIP, straight used as element of the adaptive antenna array.
The cone-shaped deployment has their own defects: time of the reception of the estimation greatly in contrast with amplitude more, phase and bags-madder- MIP, since that create amounting to zone practically instant. Also cone-shaped scan to subject to return hindrance on direction. However when the question is MIP with digital shaping signal on issue and digital processing on acceptance then with processing bending around cone-shaped scan can be executed and standard monopulse processing signal. In the event of return hindrance on direction position to purposes will allow to calculate, for instance, algorithms total-difference of the processing. Besides, signal processing with superresolution can be carried out in parallel way.
The main conclusion is concluded in that parallel combination of the cone-shaped scan DN in the aggregate with different methods of the compensations and superresolution signal can provide firm spying for purpose in condition ASHP, acting on the main and lateral petal DN antennas.
