본문주요연구료 LFM 맥충압축뢰체재근거차당정황하섭급적주요문제，포괄접수궤수발개관절환시간대근거차당적영향、근거차당정황하회파 SNR 변화화근거차당정황하적측각、측거정도적변화，병개소료감소근거차당영향가채용적조시。
Main issues related to short range eclipsing effect in linear frequency modulation (LFM) pulse compres-sion radar are analyzed, these include impact of switching time of transmit receive (T R) switch on short range eclipsing effect, as well as signal to noise ratio (SNR) variation of the echo, range and angle measurement ac-curacy in the event of short range eclipsing. Measures which can be taken to eliminate the short rang eclipsing effect are also discussed.
