Abstract

Two high-dynamic-range receiver subsystems for use in airborne radar fire control and tracking applications are described. The X -band dual-channel monopulse tracking receiver operates at 9.36±0.290 GHz with a 6-dB noise figure and a linear instantaneous dynamic range of 42 dB. A total of 80 dB of RF and IF gain control is programmable with less than ±15° phase and ±1 dB amplitude tracking errors. The Doppler radar receiver operates at 9.3±0.15 GHz and has a 4.6-dB noise figure with ⩾80 dB of instantaneous dynamic range. An 18-dB sensitivity time control (STC) circuit and a 60-dB dump attenuator allow close-in target reception
