Planetary radar high power array feed calibration

A calibration system comprising:

• a sub-reflector provided to form part of a transmitter system;
• a first receiver (RX) calibration horn disposed adjacent to a transmitter feed array of the transmitter system;
• and
• a second RX calibration horn disposed in a center of the sub-reflector,
• wherein the calibration system is configured to be used in a RX calibration process and a transmitter (TX) calibration process of the transmitter system.

A method comprising:

• performing a receiver (RX) calibration process of a transmitter system using a calibration system;
• and
• performing a transmitter (TX) calibration process of the transmitter system using the calibration system,
• wherein the transmitter system comprises (i) a transmitter feed array configured to generate a radio signal, (ii) a reflector configured to transmit the radio signal outward in a narrow beam, and (iii) a sub-reflector configured to receive the radio signal from the transmitter feed array and reflect the radio signal to the reflector before the radio signal is transmitted, and
• wherein the calibration system comprises a first RX calibration horn adjacent to the transmitter feed array and a second RX calibration horn disposed in a center of the sub-reflector.
