The invention discloses a
system and a method provided with calibration transmitting and receiving channels for real-time monitoring of multichannel transmitting and receiving delays. The method comprises the following steps of measuring a sum of
closed loop delays of a calibration transmitting channel and a calibration receiving channel, and subtracting an absolute
delay of the calibration transmitting channel from the sum of the
closed loop delays to obtain an absolute
delay of the calibration receiving channel; measuring a sum of the
closed loop delays of a reflector inter-
satellite link transmitting channel and the calibration receiving channel and a sum of the closed loop delays of a
phased array inter-
satellite link transmitting channel and the calibration receiving channel, and subtracting the absolute
delay of the calibration receiving channel from the sums of the closed loop delays to obtain absolute delays of the reflector inter-
satellite link transmitting channel and the
phased array inter-satellite link transmitting channel; and measuring a sum of the closed loop delays of the calibration transmitting channel and a reflector inter-satellite link receiving channel and a sum of the closed loop delays of the calibration transmitting channel and a
phased array inter-satellite link receiving channel, and subtracting the absolute delay of the calibration transmitting channel to obtain absolute delays of the reflector inter-satellite link receiving channel and the phased array inter-satellite link receiving channel. According to the
system and the method, the real-time monitoring of the multichannel transmitting and receiving delays is realized, and the
system and the method have the characteristic that the measured absolute delays of the transmitting channel and the receiving channel are accurate.
