The AN-SPS-10 is frequently victimized by electromagnetic emitters both on broad ship and within the fleet. Most serious interference occurs within its operating band, 5.45 to 5.825 GHz, and the second and third harmonics of its operating band. Susceptibility of the radar system to interference is due to lack of elective receiver preselectivity, intermodulation distortion and saturation within the receiver. The following modification recommendations are made Provide narrowband frequency adjustable preselector filter, Replace present mixer with high level doubly balanced mixer, Provide 80 dB out-of-hand IF rejection and high dynamic range operation, and Replace AFC mixer with image reject mixer.
- Active and Passive Radar Detection and Equipment
- Radiofrequency Wave Propagation
