A radiation sensor including an inner detector surrounded by an array of outer detectors is employed in radiation tracking apparatus which is capable of tracking a true target in a field of targets which may include a decoy or false target. The apparatus includes a color filter arrangement and a reticle which cooperates to produce pulses of long and short wavelength filtered infrared radiation upon the outer detectors of the sensor. The apparatus includes means for processing the signals produced by the outer and inner detector elements so as to discrimi...
Radiant energy sensing apparatus comprising: a spectral filter including first and second spectral bandpass portions which pass radiations of long and relatively short wavelength, respectively a centrally located detector element arranged to receive radiation passing through said first spectral bandpass portion of said spectral filter and which produces a set of signals, the amplitudes of which are a function of the position of an image of a point source target incident thereon; and a plurality of separate detectors arranged to receive radiation passing ...
