摘要： Besides a time constant circuit 5 that imposes a frequency limit on a wireless signal detected by a power detecting circuit 4 at a preset time constant Ta, there is provided a time constant circuit 8 that imposes a frequency limit on the wireless signal at a time constant Tb greater than the time constant Ta. When the signal level of an intermittent operation signal supplied from a signal input terminal 1 is H level or when a threshold processing circuit 6 decides that the level of the wireless signal is higher than a threshold Th, a logic unit 3 supplies a control signal that instructs starting to the power detecting circuit 4, time constant circuits 5 and 8 and threshold processing circuits 6 and 9.

摘要： An array antenna apparatus is obtained in which an SN ratio is improved. Antenna elements (10a - 10n) having transmission modules (20a - 20n), respectively, are arranged in plurality, wherein the plurality of transmission modules (20a - 20n) respectively have transmission signal generators (11a - 11n) that each output a transmission intermediate frequency signal (S1), local oscillation signal generators (21a - 21 n) that each output a local oscillation signal (S2), and transmission mixers (12a - 12n) that each mix the transmission intermediate frequency signal (S1) and the local oscillation signal (S2) with each other, thereby to carry out frequency conversion to a transmission high frequency signal (S3). A reference signal source (1) is provided which inputs a reference signal (Sr) to the transmission signal generators (11a - 11 n) and the local oscillation signal generators (21 a - 21 n). The transmission intermediate frequency signal (S1) and the local oscillation signal (S2) are synchronized with each other by the reference signal (Sr).
