Abstract

A plurality of substantially interference-free radar systems, each comprising:
means for generating pseudorandom waveforms for sequential transmission by radar;
and a radar transmitting and receiving phased array antenna having a horizontal beamangle of a few milli-radians (mR), and a vertical beamangle of about 25 mR.
