The Defence Research and Development Organziation (DRDO) is developing indigenous Advanced Self Protection Jammer (ASPJ) which will be equipped on Tejas LCA MK-1, MK-1A, MK-2 and Su- 30MKI fighter jets. As of now one (1) unit is undergoing Flight Testing; while another unit has been received for testing recently.
TEJAS ASPJ will use 16 element Active Transmit Receive Unit (ATRU) and MK-1 one will use 32 element ATRU. Noteworthy, this ASPJ is based on the advanced solid-state gallium arsenide (GaAs) based active electronically scanned array (AESA) unit technology or gallium nitride (GaN)-based solid-state active electronically scanned array (AESA) jammer transmitters.
