Pakistan is expected to unveil an indigenously developed ActiveElectronically Scanned Array (AESA) radar which will be deployed in bothground-based and airborne roles.
AESA is a second-generation phased radar in which radio waves of multiplefrequencies can be sent in different directions without moving the antenna.AESA radars allow aircraft and ships to send powerful signals whileremaining stealthy and resistant to jamming.
According to details, Pakistan’s local AESA radar is being developed by theAir Weapon Complex (AWC), an R&D facility of the Pakistan Air Force (PAF),in collaboration with the National University of Science and Technology(NUST).
Although complete details of the radar are unavailable at the moment,sources have claimed that the indigenously developed AESA radar will usethe latest gallium nitride (GaN) transmit and receive modules that areowned by only a few countries.
AWC reportedly designed two types of GaN transmit and receive modules-S-band and X-band- in late 2019 and early 2020 respectively.

Both modules have different functionalities. The S-band module is used inground-based and airborne search radars for target search and detection. Onthe other hand, the X-band module is associated with fire control due toits superior resolution.
The indigenous AESA radar is expected to officially make its debut in theJF-17 Block 4 fighter jet or the fifth-generation stealth fighter jet beingdeveloped under Project Azm.
