Claims

[Scope of utility model registration request]

A large number of active antenna elements that transmit and receive rake waves are arranged, and by controlling the phase shift of the transmitted wave phase and the received wave phase of each active antenna element,
In an active phased array radar that controls the direction of a radar beam, the phase shift (phase amount) that occurs in the transmitting system and receiving system of each of the above active antenna elements is detected and stored in advance. An active phased array radar characterized in that the above-mentioned phase-side control amount is controlled in accordance with a phase amount.
