RECEIVING ARRANGEMENT FOR A MONOPULSE RADAR Russian patent published in 2007 - IPC G01S13/44 

FIELD: the invention refers to receiving arrangements for a monopulse radar and may be used in the modes of tracking and predictable survey.

SUBSTANCE: the achievable technical result is in increasing accuracy of estimation of an angle of misalignment due to diminishing the influence of equipment errors and its own noises. For this purpose an output signal of a receiving arrangement is formed in the shape of ratio where Σ and Δ are signals of summary and differential channels which provides the outmost level of the output signal in the direction to the target. The arrangement has a two-channel antenna with a summary-differential transformer each exit of which through in-series switched a radio set and an amplitude detector is connected to the inputs of a subtracter and an adder, whose outputs are switched through a divisor to the output of the arrangement.

EFFECT: increases accuracy of estimation of a misalignment angle.
