Amplitude-comparison monolulse for CWRadar low-altitude target elevation off-line measurement

Phase-comparison monolulse was adopted in CWradar system,In the presence of sea-surface multi-path CW radar measure a low elevation target is difficulty, and its precision can´t satisfy the requirement of ballistic trajectory measurement in shooting range. The bias compensation algorithm of Amplitude-comparison monopulse had been calculated the elevation of low-altitude after measurement from the deposited video frequency signal by the CWradar system. The results indicate this method is effective and feasible in the off-line elevation extraction and it can improve the precision of elevation measurement.
