Abstract

To improve the performance of identification for radars in an ES(Electronic warfare Support) system, it is necessary to estimate scan characteristics as well as the basic identification parameters such as frequency, pulse repetition interval and pulse width of radars. This paper presents the method of estimating the scan period and the scan beam width of circular scanning radars. The proposed method estimates the scan period using the quality of the autocorrelation of a periodic signal. And, it estimates the scan beam width using the linear interpolation and the proposed method of estimating the scan period. Simulation results are presented to show the performance of the proposed method.

ES 시스템에서 레이더를 식별하는 능력을 향상하기 위해서는 주파수, 펄스반복주기 및 펄스폭 등과 같은 기본 식별변수 이외에 스캔특성을 추정하는 기법이 필요하다. 본 논문에서는 원형스캔 레이더의 스캔특성인 스캔주기와 스캔빔폭을 추정하는 방법을 제안하였다. 제안된 방법은 주기함수의 자기상관관계 특징을 이용하여 스캔주기를 추정한다. 그리고 제안된 스캔주기추정기법과 선형 보간법을 이용하여 스캔빔폭을 추정한다. 제안한 방법의 성능을 입증하기 위해 다양한 모의신호에 대한 실험결과를 제시하였다.
