The invention relates to the microwave technical field, and particularly relates to a waveguide two-dimension single-pulse sum-difference network. The waveguide two-dimension single-pulse sum-difference network comprises a phase shifting network, a first-stage 3dB coupling network and a second-stage 3dB coupling network which are connected in sequence; the phase shifting network comprises four phase shifting waveguides in parallel; the first-stage 3dB coupling network comprises four coupling waveguides I in parallel; and the second-stage 3dB coupling network comprises four coupling waveguides II in parallel, wherein the corresponding phase shifting waveguides, the coupling waveguides I and the coupling waveguides II form a first network waveguide, a second network waveguide, a third network waveguide and a fourth network waveguide correspondingly. The waveguide two-dimension single-pulse sum-difference network adopts the combination form of a 3dB waveguide broad-side coupler and a 3dB waveguide narrow-side coupler; the overall structure is formed by only four waveguides in parallel, and the waveguides share the waveguide broad walls and the waveguide narrow walls; and in addition, transitional waveguide between the couplers is not required, instead, the couplers are connected directly, so that compact structure and simple and convenient processing are achieved.
Description
technical field [0001] The invention relates to the field of microwave technology, in particular to a waveguide two-dimensional single pulse sum difference network. Background technique [0002] The sum-difference network is also called a summator, a comparator or a monopulse processor. The two-way or four-way independent signals can perform sum-difference comparison operation and can output the sum-difference signal at the same time, so as to obtain the angle error signal and realize target tracking. [0003] Usually, the received signals of the two quadrants of the one-dimensional monopulse antenna are compared with the sum and difference once, and can only output the sum signal and the azimuth difference signal or the elevation difference signal. Pitch or first pitch and then azimuth to compare the sum and difference, and finally output the sum signal, azimuth difference signal and pitch difference signal at the same time. Compared with the sum-difference network in the...
