Method for adjusting lobe of radiation pattern of plane radar antenna in airborne vehicle i.e. airplane, involves selecting sign of value of maximum phase at ends of antenna according to desired distribution of radiated energy

摘要

The method involves selecting a sign of value of maximum phase at ends of an array type radar antenna i.e. plane radar antenna, according to desired distribution of radiated energy in front of the antenna. A control signal is transmitted by an inlet and delivered to sub-arrays of an electronically-scanned antenna, where each sub-array includes four aerial radiation elements. The desired distribution is considered in any point of a zone located at a distance from center of the antenna. An independent claim is also included for an array type radar antenna.
