ABSTRACT:
A pseudo-noise modulated continuous wave radar for providing foliage penetion as a means for quickly establishing perimeter surveillance of an emplacement in heavily foliaged environments. An RF signal is radiated into free space by means of a static antenna array. The return signal is received by the receiving antenna which is composed of eight-dipoles, phased to create three receive lobes. The three lobes are utilized in an amplitude monopulse technique to determine the azimuthal direction to the detected target with respect to the radar site.
