16  Category XI—Military Electronics
 (a) Electronic equipment and systems not included in Category XII, as follows:
 (1) underwater hardware, equipment or systems, as follows:
 (i) active or passive acoustic array sensing systems or acoustic array equipment capable of real‑time processing that survey or detect, and also track, localise (that is, determine range and bearing), classify, or identify, surface vessels, submarines, other undersea vehicles, torpedoes, or mines, having any of the following:
 (A) multi‑static capability;
 (B) operating frequency less than 20 kHz;
 (C) operating bandwidth greater than 10 kHz;
 (ii) underwater single acoustic sensor system that distinguishes non‑biologic tonals and locates the origin of the sound;
 (iii) non‑acoustic systems that survey or detect, and also track, localise (that is, determine range and bearing), classify, or identify, surface vessels, submarines, other undersea vehicles, torpedoes, or mines;
 (iv) acoustic modems, networks, and communications equipment with real‑time adaptive compensation or employing Low Probability of Intercept (LPI);
 (v) low Frequency/Very Low Frequency (LF/VLF) electronic modems, routers, interfaces, and communications equipment, specially designed for submarine communications;
 (vi) autonomous systems and equipment that enable cooperative sensing and engagement by fixed (bottom mounted/seabed) or mobile Autonomous Underwater Vehicles (AUVs);
 (2) underwater acoustic countermeasures and counter‑countermeasures systems or equipment;
 (3) radar systems and equipment, as follows:
 (i) airborne radar that maintains positional state of an object or objects of interest, other than weather phenomena, in a received radar signal through time;
 (ii) Synthetic Aperture Radar (SAR) incorporating image resolution less than (better than) 0.3 m, or incorporating Coherent Change Detection (CCD) with geo‑registration accuracy less than (better than) 0.3 m, not including concealed object detection equipment operating in the frequency range from 30 GHz to 3,000 GHz and having a spatial resolution of 0.5 milliradians up to and including 1 milliradians at a standoff distance of 100 m;
 (iii) Inverse Synthetic Aperture Radar (ISAR);
 (iv) radar that geodetically‑locates (that is, geodetic latitude, geodetic longitude, and geodetic height) with a target location error 50 (TLE50) less than or equal to 10 m at ranges greater than 1 km;
 (v) any Ocean Surveillance Radar with an average‑power‑aperture product of greater than 50 Wm2;
 (vi) any ocean surveillance radar that transmits a waveform with an instantaneous bandwidth greater than 100 MHz and has an antenna rotation rate greater than 60 revolutions per minute (RPM);
 (vii) air surveillance radar with free space detection of 1 square metre RCS target at 85 nmi or greater range, scaled to RCS values as RCS to the 1/4 power;
 (viii) air surveillance radar with free space detection of 1 square metre RCS target at an altitude of 65,000 feet and an elevation angle greater than 20 degrees (that is, counter‑battery);
 (ix) air surveillance radar with multiple elevation
