Abstract

A pulse radar signal is characterized by periodic pulses and noise components between them. In this Letter, we present a test statistic for detecting the presence of a pulse radar which exploits the inherent characteristics of a pulse radar signal by the ratio of maximum power to minimum power from the received signal and compares its sensing performance with that of the energy detector by computer simulation in a variety of situations.

펄스 레이다 신호는 펄스가 주기적으로 나타나며 그 이외 시간 구간에서는 잡음만 나타나는 형태를 갖는다. 본 논문에서는 이러한 특징을 효과적으로 반영하는 검출 방식을 모색하기 위하여, 관측 기간 내에 존재하는 수신 신호 샘플로부터 최대 전력과 최소 전력 간의 비율을 검정 통계량으로 사용하는 방식을 제안하고, 모의 실험을 통해 다양한 환경에서 해당 방식의 성능을 에너지 검파 방식과 비교하고자 한다.
