Compensation technique to measure angular monopulse receiver with amplitudes comparison.

摘要

MONOPULSE DESCRIBED RECEIVER OFFSET AMPLITUDE COMPARISON (10) having a capacity of SUBSTANTIALLY ANGLE MEASUREMENT INACCURACIES IN THE unaffected by the channel response imprecision TRANSIENT AND WHITE WIDTH tracing functionality. RECEIVER MONOPULSE of this invention (10) includes a first channel receiver (24) TO IMPRESS A first output voltage S1 IN A first output port (28) in response to excitation by the signal SUM. RECEIVER IMPRESIONA a second channel (26) having a second output voltage S2 IN A second output port (30) in response to excitation SIGNAL sum and difference. In one calibration, calibration source (22) PROVIDES A SERIES OF PULSES CALIBRATION CHANNELS first and second (24, 26) including first and second voltages calibration APPEAR IN THE FIRST AND SECOND OUTLET PORT (28, 30). GATES OF SAMPLING (32, 34) SAMPLE first and second calibration voltage after application of each pulse CALIBRATION FOR RECEIVER first and second channels (24, 26). MODE debugging by THE DOORS OF SAMPLING (32, 34) are operative to sample first and second PRESENTS VOLTAGE OUT IN THE FIRST AND SECOND outlet port (28, 30). The receiver 10 also includes a circuit (48, 50) to calculate the location ANGLE OF FIRST PURPOSE OF THE FIRST AND INVENTORY second voltages. A compensation network (36) ADJUSTED AFTER SPOTTING ANGLE BASED ON VOLTAGE CALIBRATION INVENTORY.
