AN/ALQ-153

AN/ALQ-153 is an airborne range gate pulse-Doppler tail warning radar for detecting anti-aircraft missiles, protecting Rockwell B-1B Lancer and B-52G/H Stratofortress aircraft. It replaced the RCA AN/ALQ-127, introducing a solid-state transmitter, frequency-agile waveform and digital processor using non-scanning antennas that have low backlobes. The ALQ-153 was originally manufactured by Westinghouse Electric Corp, now supported by Northrop Grumman.
