锁定是一个不怎么严格的词语。single target tracking/stt是一个效果。STT和TWS多目标跟踪在使用多普勒雷达的三代机中通常和连续波照射无关。
半主动导弹并不一定使用连续波来制导。因此使用apg-68的f-16可以发射aim-7。但是制导半主动弹将需要多普勒雷达相对于stt提高PRF和duty factor。
The F-16 is equipped with either the APG-66 (F-16A) or APG-68 (F-16C) Westinghouse multimode radars. Both radars have been frequently upgraded and exhibit the latest in radar technology, including a very high-speed integrated circuit (VHSIC) signal processor. These radars provide long-range detection and tracking and high-resolution mapping. Popular air-to-air modes include air combat (auto acquisition), range while search, search while track (two-target), 10-target track-while-scan, and raid cluster resolution. Air-to-surface modes include moving target track, high-resolution mapping, and sea search and track. The APG-68 also has a high-pulse-repetition-frequency (PRF) capability for very long-range detection and for guidance of AIM-7 missiles. AIM-7 capability can be provided with either radar by adding a continuous wave illuminator (CWI).
Future growth may include auto terrain following, advanced aerial target identification, combined and interleaving of mode, and a synthetic aperture radar (SAR) capability. SAR provides very high resolution mapping and target recognition capability with all-weather precision weapons currently in development. Guidance System Raytheon semiactive on either continuous wave or pulsed Doppler radar energy F-16 Block 30/32 - Common engine bay introduced at Block 30/32 (deliveries from July 1986) to allow fitting of either P&W F100 PW-220 (Block 32) or GE F110-GE-100 (Block 30) Alternate Fighter Engine. Other changes include computer memory expansion and seal-bonded fuselage fuel tanks. First USAF wing to use F-16C/Ds with F110 engines was 86th TFW at Ramstein AB, Germany, from October 1986. Additions in 1987 included full Level IV multitarget compatibility with AMRAAM (as Block 30B), voice message unit. Shrike anti-radiation missiles (from August), crash survivable flight data recorder and modular common inlet duct allowing full thrust from F110 at low airspeeds. Software upgraded for full Level IV multitarget compatibility with AMRAAM early 1988. Industry-sponsored development of radar missile capability for several European air forces resulted in firing of AIM-7F and AIM-7M missiles from F-16C in May 1980; capability introduced mid-1991; missiles guided using pulse Doppler illumination while tracking targets in a high PRF mode of the AN/APG-68 radar.
