OVERVIEW:  The Type 1022 radar is a shipborne, long-range, 2-D surveillance and target indication radar operating in the NATO D-band (IEEE L-Band).

DETAILS:  The Type 1022 was developed as a replacement for the Royal Navy's Type 965 and 992Q surveillance radar.  It uses solid-state electronics and features a pulse-compression receiver with Moving Target Indicator (MTI) providing for good performance in rain and in the presence of surface clutter. The antenna uses a squintless feed to provide tapered illumination of the main reflector. This results in good sidelobe performance across the band.   It also features frequency agility over a wideband, horizontal and circular polarization.  

These features give it improved capability to track low-flying aircraft and when operating against radar jamming or a high clutter environment.

Specifications:

	Frequency:	 1.215-1.400 GHz (D-band (NATO))
	PRF:		??
	Power: 		 150 kW (peak); 5 kW (average)
	Range:		225 nm (instrumented);  				
	Accuracy:	?? m (range);  ?? min (aziumth); ??min (elevation)
			
NOTES:  IOC 1978.  The Type 1022 is based on the  Dutch LW-08 radar.
