ABSTRACT:
A compressive receiver (10) includes a modulation circuit (14) that modulates the receiver input signal with compensation values equal to the ratio of the transfer function of an ideal linear dispersive delay line to that of the main compressive-receiver linear dispersive delay line (22). An auxiliary linear dispersive delay line (16) dispersively delays the results modulated signal at the reciprocal of the compressive receiver's chirp rate, and the resultant signal is progressively translated in frequency by a frequency translator (18) at the compressive-receiver chirp rate. As a consequence, each point in a signal-frequency component of the input signal is translated to the frequency at which the compensation function was evaluated in modulating the component at that point in time, so the departure of the main dispersive delay line (22) from linearity is compensated for, and increased dynamic range results.
