  This paper is an attempt to mitigate the beam squint happening due to
frequency-dependent phase shifts in the wideband beamforming scenario,
specifically in radar applications. The estimation of the direction of arrival
is significant for precise target detection in radars. The undesirable beam
squint effect due to the phase shift-only mechanism in conventional phased
array systems, which becomes exacerbated when dealing with wide bandwidth
signals, is analyzed for a large set of steering angles in this paper. An
optimum baseband delay combined with the phase shift technique is proposed for
wideband radar beamforming to mitigate beam squint effectively. This technique
has been demonstrated to function properly with 1-GHz carrier frequency for
signals with wide bandwidths of up to +/-250MHz and for steering angles ranging
from 0 to 90 degrees.
