Selected tendencies of modern radars and radar systems development

This paper presents modern radars and radar systems problems caused by troubles and dangers connected with actual battlefield conditions. The usefulness of the phased array radar (PAR), low probability of intercept (LPI) radar and the multi-junction radar (MFR) has been described from the point of view of the single radar using. Moreover chosen aspects of the modem radar systems development, including among others over the horizon (OTH) radars and airborne early warning (AEW) radars, has been discussed too.
