Abstract
A receiver in a radar system has two feed horns which supply a hybrid. The ybrid sums the amplitude of the signals from the feed horns at its first output and subtracts the signals at its second output. The outputs are each converted to I.F. by mixers, de-chirped, and then are coherently integrated. The integrated output of the difference is fed to a servo for tracking. The integrated output of the sum is fed through a control unit to control the beat signal of the mixers.
Claims7
A radar system comprising receiver means receiving pulse echoes from a reflecting means and having a first and a second output, said first output being the sum of pulse echoes received by two spaced means in said receiver means, said second output being the difference between the magnitude of the pulse echoes received by said two spaced means, first and second channel units connected to said first and second outputs respectively, and each channel unit comprising a converter means connected to one output of said receiver means for converting the output to I. F. signals, integrating means connected to an output of the converter means for coherently integrating data from a predetermined number of pulse echoes, and utilization means connected to an output of said integrating means.
