Transmission system (12 1 ) of elements (3 1 ) to (3 n ) via (7 n ).
To (12 n ). Microwave signal is an element (3 1 )
~ (3 n ) transmission system (12 1 ) ~ (12 n ) phase controller (1

Is emitted from the space. The microwave signal radiated into the space is reflected by the target, is again received by the element antennas (6 1 ) to (6 n ), and passes through the duplexer (11 1 ) to (11 n ) to the element (3 1 ). It is transmitted to ~ (3 n) of the reception system (15 1) ~ (5 n ). Microwave signal input to the receiving system (15 1) ~ (15 n ) is amplified by a low noise amplifier (16 1) ~ (16 n ). The microwave signal amplified by the low noise amplifier (16 1 ) to (16 n ) is directly or converted to IF, and its output contains the phase and amplitude information by the analog-digital converters (17 1 ) to (17 n ). Converted to digital signal. The digital signal is transmitted through the signal lines (9 1 ) to (9 n ) of the receiving system, and the individual Fourier transform, fast Fourier transform, and Win are performed in the digital beam forming circuit (10).
Beams are combined as digital signals rather than as microwave signals using techniques such as ograd Fourier transform. Therefore, a plurality of signals from each element (3 1 ) to (3 n ) can be digitally processed in parallel according to an arbitrary beam shape. In addition, since information from all elements (3 1 ) to (3 n ) can be effectively processed at all times, information from all directions of the half space can be obtained at all times.

される。Even if linearly polarized antennas are used as the element antennas (6 1 ) to (6 n ), the polarization of the transmission signal and the polarization of the reception signal reflected from the target are different from each element antenna (6 1 ) to (6 n ). It is the same for each n ), and the signal from the target is converted into a digital signal containing phase and amplitude information in the stages of elements (3 1 ) to (3 n ) and this is converted into a digital beam forming circuit (10). The problem of cross polarization due to the difference in polarization between the elements can be solved since they are combined.
