METHOD FOR IMPROVING POSITION ESTIMATION PERFORMANCE BY SUPPRESSING SIDELOBE CLUTTER OF RANDOM PHASE MODULATION SIGNAL AND UWB RADAR SYSTEM FOR PREVENTING COLLISION IN MULTI-PATH ENVIRIONMENT

摘要

Disclosed are a technique for improving position estimation performance through side lobe removal of a noise-based phase modulation waveform and a wideband radar system for preventing collision in a multipath environment, and a wideband radar mounted to prevent collision between unmanned aerial vehicles according to an embodiment of the present application A method for improving position estimation performance in a system includes, at a transmitting end of the wideband radar system, dividing a wideband signal into a plurality of band signals corresponding to a plurality of frequency bands, and performing noise-based phase modulation for each of the band signals. and removing, at the receiving end of the wideband radar system, a side-lobe component of each of the band signals reflected back from a predetermined target.
