OVERVIEW: The  YLC-29 is a mobile, bistatic passive detection system designed to detect radiofrequency emitting targets. 

DETAILS: This detection system is a bi-or-multi-static passive detection system that uses at least one, and ideally three or more commercial radio or TV signals reflected from a moving airborne target to passively detect it.  Using  one transmitter, it likely can provide a two-dimensional track,  but not altitude, resolution and accuracy improve with more civilian transmitters.  It reportedly can also detect stealth aircraft and other low signature targets.  

Because it is not emitting, it is less susceptible to ECM.

The YLC-29 likely supplements the YLC-8B, SLC-7 and SLC-12 radars to provide an integrated stealth aircraft detection capability.
