Problem Statement

Modern Radars operate in dual bands to meet search and precise tracking requirements. Dual-Band radar as a protection mechanism is installed in aircraft for protection against hostile entities like missiles. A Missile approach warning sensor that triggers the countermeasure consists of a dual-band RF system that needs a dual-band antenna.  Currently, the industry needs onboard dual-band radars for advanced ECM mechanism. The shared aperture antenna along with a laser outlet is an integral part of the system. The development of these antennas will enable the indigenous development of high precision dual-band radars.

Objective of the project

The objective of this project is to design a shared aperture of antennas catering to both low band and high band as required by the Dual Band Radars. The low band antenna will be operating at L band (1.2GHz) whereas the high band antenna will be operating at Ka band (30GHz). The design of the antenna should cater for the laser locating at the center of the aperture.
