Abstract:

In combination with an envelope detector in a radar system, a bias compensation circuit consisting of a programmable read-only memory and a binary adder produce an unbiased envelope detection signal. The bias compensation circuit adds one to the output of the detector based upon whether the minimum of the I and Q inphase and quadrature signals is odd and the maximum even. It is capable of compensating for both normal envelope detection and the multiple divide-by-two case. As a result the dynamic range of the radar can be increased without the necessity for extensive additional hardware.
