The AN/APQ-120 was an aircraft fire control radar (FCR) manufactured by Westinghouse for the McDonnell Douglas F-4E Phantom II. AN/APQ-120 has a long line of lineage, with its origin traced all the way back to Aero-13 FCR developed by the same company in the early 1950s.

AN/APQ-120 was operating in X band fully solid-state fire-control radar used in McDonnell Douglas F-4D/E/F/G “Phantom”. It was a pulse-Doppler radar and was developed by Westinghouse in 1967.

APQ-120 雷达采用了许多晶体管器件，这主要是为了减小体积和重量，适应 F-4E 机头下方布置固定机炮的需要，同时也提高了可靠性。 该雷达采用 AYK-14 计算机后也被称为 AWG-14 火控系统（原编号 AWG-10A，因为 AYK-14 是 F-4J 上 AWG-10 火控系统计算机的改型）。 该计算机比 APQ-120 以前使用的目标拦截计算机能提供更有效的武器发射方程解算，尤其是在使用“麻雀”导弹时计算方程能考虑目标的机动情况，使“麻雀”从拦射导弹转变成现代意义上的超视距空空导 …

2024年5月16日 · The AN/APQ-120 is a late-60s radar system developed to satisfy the requirements of the F-4E Phantom II. Due to technological and practical limitations, it cannot provide the same wide variety of azimuth and elevation options as modern devices.

an/apq-100 是 an/apq-72 的换代型号，其抛物面天线是二代机雷达的典型特征。 作为空军 F-4 换代型号的 F-15 大量采用新材料，新工艺等措施减轻重量，自重较 F-4 明显下降，但其 AN/APG-63 火控雷达的天线孔径不但没有缩小，反而进一步增大到了 33 英寸/84 厘米。

AN/APQ-120雷达是西屋电气（Westinghouse）为F-4各型飞机研制的雷达序列中的最后一个型号，采用脉冲连续波体制。 1967年至1980年已生产2000部，APQ-120已用新的数字计算机改进。

威斯汀豪斯apq-120是一款早期的“固态”雷达（源自apq-109），而固态元件必须采取措施减少明显的振动，尤其当在六十年代的电子设备旁边安装一门巨大的加特林机炮的时候！

而后来的F-4E战斗机使用了更新的 AN/APQ-120雷达 ，该火控雷达采用了脉冲波形和连续波制导的体制，是一款具备空空与空地方式的多功能雷达，它采用了晶体管电路和固态电路，同时还具备一定的下视能力。AN/APQ-120重量为290kg，峰值功率为165kW，对小目标的最大 ...

The Westinghouse AN/APQ-120 Fire Control Radar, a continuation of the F-4C's -100 and the 4D's 109, is a solid state pulse radar providing the F-4E with air to air intercept functionality, air to ground mapping, ground target reference provision to the LABS and WRCS bombing systems, as well as radar beacon capability.
