PRF APPARATUS AND METHOD FOR SELECTING PRF OF VIDEO RADAR

The present disclosure relates to a method for selecting a PRF of an image radar, which comprises the steps of: inputting at least one of a target range ambiguity-to-signal ratio (RASR) and a target azimuth ambiguity-to-signal ratio (AASR); selecting maximum and minimum PRFs; calculating a first PRF...

Zusammenfassung:	The present disclosure relates to a method for selecting a PRF of an image radar, which comprises the steps of: inputting at least one of a target range ambiguity-to-signal ratio (RASR) and a target azimuth ambiguity-to-signal ratio (AASR); selecting maximum and minimum PRFs; calculating a first PRF on the basis of the maximum and minimum PRFs; calculating at least one of an RASR and an AASR on the basis of the calculated first PRF; and determining whether to select the first PRF as a final PRF by comparing at least one of the calculated RASR and AASR with at least one of the target RASR and the target AASR. Accordingly, interference due to a distance and azimuth ambiguity can be minimized when operating an image radar. 본 개시는 목표 RASR(Range Ambiguity to Signal Ratio) 및 목표 AASR(Azimuth Ambiguity to Signal Ratio)중 적어도 하나가 입력되는 단계, 최대 PRF 및 최소 PRF를 선택하는 단계, 최대 PRF 및 최소 PRF에 기초하여 제1 PRF를 산출하는 단계, 산출된 상기 제1 PRF를 기초로 RASR 및 AASR 중 적어도 하나를 계산하는 단계, 계산된 RASR 및 AASR 중 적어도 하나를 목표 RASR 및 AASR 중 적어도 하나와 비교하여 제1 PRF를 최종 PRF로 선정할지 여부를 판단하는 단계를 포함하는 방법을 제공함으로써 영상 레이다를 운용할 시에 거리 및 방위 모호성으로 인한 간섭을 최소화 할 수 있다.
