Radar guidance system that corrects phase errors induced by channel to channel the hardware.

摘要

A GUIDE TO RADAR SYSTEM DEPENDENT OF A PHASE, WHICH RECEIVER RETURNS TO SPREADING CHANNEL (22) WHERE IN ADDITION RETURNS (S) AND CHANNEL BACK (24) WHERE THEY DIFFER RETURNS (JD). SIGNALS SY JD COMBINE (26) and formed into two channels BACK AS S + JD Y S-JD, both pass through amplifiers CONTROLLED AGC (28, 30) within a DETECTOR phase angle (32) PROVIDES THE ANGLE LENS (BETA) THE MIRA. APPLY a test signal to the receiver with JD = O, the output value DETECTOR phase angle (32) for various values ​​of attenuation AGC is stored by a digital processor (34), and the processor (34) AMENDING PHASE VALUE MEASURED WITH TARGET VALUES STORED FOR CORRECTING ERRORS INDUCED to the AGC amplifier.
