OVERVIEW:  The  N001E Myech aka SLOT BACK aka RPLK-27  radar is an  air-to-air,  medium-range, fire-control  radar operating in the NATO I/J (IEEE X) band.

DETAILS: 
 The  N001E Myech aka SLOT BACK pulse-Doppler radar uses a  mechanically steered twist-Cassegrain antenna.  The antenna design is a  scaled-up copy of the N019 radar, and it uses the same TS100 processor.

The N001 is a Look Down/Shoot Down (LD/SD) and track-while-scan capable radar capable of  tracking up to 10 targets, and engaging one target at a time.  It is also capable of tracking ECM sources.
