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 beams, phase or amplitude monopulse estimation, or 3D height‑finding;
 (x) air surveillance radar with a beam solid angle less than or equal to 16 degrees2 that performs free space tracking of 1 square metre RCS target at a range greater or equal to 25 nmi with revisit rate greater or equal to 1/3 Hz;
 (xi) instrumentation radar for anechoic test facility or outdoor range that maintains positional state of an object of interest in a received radar signal through time or provides measurement of RCS of a static target less than or equal to minus 10dBsm, or RCS of a dynamic target;
 (xii) radar incorporating pulsed operation with electronics steering of transmit beam in elevation and azimuth;
 (xiii) radar with mode(s) for ballistic tracking or ballistic extrapolation to source of launch or impact point of articles controlled in Categories III, IV, or XV;
 (xiv) active protection radar and missile warning radar with mode(s) implemented for detection of incoming munitions;
 (xv) over the horizon high frequency sky‑wave (ionosphere) radar;
 (xvi) radar that detects a moving object through a physical obstruction at distance greater than 0.2 m from the obstruction;
 (xvii) radar having moving target indicator (MTI) or pulse‑Doppler processing where any single Doppler filter provides a normalised clutter attenuation of greater than 60dB;
 (xviii) radar having electronic protection or electronic counter‑countermeasures (ECCM) other than manual gain control, automatic gain control, radio frequency selection, constant false alarm rate, and pulse repetition interval jitter;
 (xix) radar employing electronic attack (EA) mode(s) using the radar transmitter and antenna;
 (xx) radar employing electronic support (ES) mode(s) (that is, the ability to use a radar system for ES purposes in one or more of the following: as a high‑gain receiver, as a wide‑bandwidth receiver, as a multi‑beam receiver, or as part of a multi‑point system);
 (xxi) radar employing non‑cooperative target recognition (NCTR) (that is, the ability to recognise a specific platform type without cooperative action of the target platform);
 (xxii) radar employing automatic target recognition (ATR) (that is, recognition of target using structural features (for example, tank versus car) of the target with system resolution better than (less than) 0.3 m);
 (xxiii) radar that sends interceptor guidance commands or provides illumination keyed to an interceptor seeker;
 (xxiv) radar employing waveform generation for LPI other than frequency modulated continuous wave (FMCW) with linear ramp modulation;
 (xxv) radar that sends and receives communications;
 (xxvi) radar that tracks or discriminates ballistic missile warhead from debris or countermeasures;
 (xxvii) bi‑static/multi‑static
