Construction of a radiophotonic receiving channel with the optical heterodyning for APAA is considered together with the fiber-optic distribution system for digital and analog signals. The receiving channel of the microwave band is built on the basis of stabilized CW laser, amplitude modulators and narrow-band optical filters to convert the radar signal into the low frequency band. Characteristics of such a receiving channel are evaluated, and optimal operating regimes are found. For X band radar, the scheme of construction of APAA fiber-optic transmission systems is considered. Characteristics of the main parts of the system are presented.
