Embodiment Construction

[0025] Hereinafter, an array antenna transceiver according to the present invention will be described in detail with reference to the accompanying drawings.

[0026] FIG. 2 shows a block diagram illustrating the structure of an array antenna transceiver constructed according to an embodiment of the present invention. The array antenna transceiver in this embodiment has a redundant structure for the reference signal, and in this redundant structure, when the common reference signal generating part fails to operate normally or cannot detect the reference signal output by the common reference signal generating part When using a signal, the system can be switched to a system that utilizes individual reference signal generation sections.

[0027] Referring to Fig. 2, the array antenna transceiver includes an antenna part 101, N transceiver blocks 102-1 to 102-N, a transceiver part control circuit 109, an alarm signal detection circuit 110, a hybrid coil circuit (distribution circui...

Abstract

An array antenna transceiver includes an antenna section 101, N transceiver blocks 102, a common reference signal generating section 112, 111 and a transceiver control section 109. The N transceiver blocks are connected to the antenna elements. Each of the N transceiver blocks generates an individual reference signal. The transceiver block carries out transmission of a transmission signal and reception of a reception signal based on an common reference signal using a corresponding antenna element as a part of an array antenna in an array mode and based on said individual reference signal using the corresponding antenna element as an individual antenna element in an individual mode.

Description

technical field [0001] The present invention relates to an array antenna transceiver, and more particularly, the present invention relates to an array antenna transceiver capable of continuous transmission and reception even when a failure occurs in a reference signal supply system. Background technique [0002] The array antenna transceiver has a transceiver section provided for each array antenna element and a transceiver section control circuit for controlling them. When receiving, the array antenna transceiver performs frequency conversion processing on the signal received by each antenna unit in the transceiver part and sends it to the control circuit of the transceiver part, and the control circuit of the transceiver part performs weighting operation and synthesis operation. When transmitting, the signal is weighted in the control circuit of the transceiver section and sent to the transceiver section, and the transceiver section performs frequency conversion transmissi...
