Radio receiver for MM range suitable for mobile military use - has structural and spatial alignment, identical reception modules in two spaced, vertical groups

摘要

Identical receiver modules (1a-10a; 1b-10b) w.r.t. the construction and three-dimensional alignment are arranged in groups (a, b) with fixed spacing above each other. The receiver module of the first groups (a) are coupled to a first summation circuit (20a), while the receiver modules of the second group (b) are coupled to a second summation circuit (20b). The two summation circuits are coupled with their outputs to the radio receiver output (60) via a change-over switch (50). The receiver modules within a group are so closely stacked that the correlation of their output signals is at least 0.5. The spacing of the two groups is so chosen that the correlation of the receiver module output signal from both groups is below 0.5. USE/ADVANTAGE - Military flotillas, etc., with reliable signal reception even under unfavourable conditions.
