Title:
MULTIPLEXED CHANNEL BEAM FORMING DEVICE
Document Type and Number:
Japanese Patent JPH10294703
Kind Code:
A
Abstract:

To reduce power loss and weight by receiving plural channel signals along each direction that is defined by an array rope, with which a collector array means is related to an collector array means.

Power amplifiers 10 to 12 and band-pass filters 20 to 22 are cascaded to each of sources 30 to 32 respectively that is constituted of a horn on the side of an upstream. After channel signals S0 to S2 which are sent as an identical beam are amplified by the amplifiers 10 to 12 respectively, they are filtered by the corresponding filters 20 to 22, and the horns 30 to 32 separately emit waves R0 to R2. Focusing means 40 to 42 which are constituted of concave reflecting elements reflect the waves towards a collector array 50. The array 50 operates at the time of receiving the waves, generates plural maximum values that are almost the same amplitudes as in a direction corresponding to the emitting direction of the waves R0 to R2 and oscillates a channel signal which is combined from a transmission array 51 toward a parabola 6.
