SHORT WAVE RADAR DEVICE

摘要: PURPOSE:To obtain a short wave radar device which can detect target signal without embedding in sea clutter or its side lobe by removing blind area due to the on Doppler frequency axis using surface wave. CONSTITUTION:A plurality of different frequencies are transmitted and received simultaneously time-sharing manner, their signals suppressed at filter 19, Doppler-filtered separator 3, detected detector, results so corrected corrector 20 as coincide target, ORed an OR calculator 21 output hit report.
