Title: Clutter suppression system for radar - uses twin channel, phase shifting and homodyne multiplication
Inventor: MATTERN JOHN
IPC: G01S7/36
Filed: 1972-08-28
Abstract: The clutter suppression system comprises a range-gate and receiver-gate with twin mixers and a 90 deg. hybrid circuit to produce 90 deg. phase-shifted signals of the Doppler frequency and the blanking frequency of the range gate. The signals are processed in separate channels of a homodyne multiplier. The clutter and Doppler signals pass through frequency -compensation networks and variable bandpass filters of the four-terminal type. The filtered signals are then processed by two 90 deg. phase-difference systems, each comprising RC low-pass and high-pass filters. Two further pairs of channel signals are produced and these are cross-coupled to two 4-quadrant precision multipliers which operate on a pulse-width principle. The outputs of the multipliers are taken to a subtraction stage, the output of which is filtered and passes through a threshold detector. The resulting signal is used to indicate the movement and direction of the target.
