Abstract
본 발명은 레이다 시스템의 인티그레이션 방법 및 인티그레이션 장치에 관한 것으로, 인티그레이션 방법은 레이다 시스템의 S/N비를 향상시키기 위한 인티그레이션 방법에 있어서, 현송신펄스로부터 수신되는 신호 값V(p,r)와 전 펄스까지의 인티그레이션 결과의 궤환된 값 E(p-1,r)값을 비교하는 단계, 상기 비교값에 따라 V(p,r)이 E(p-1,r)보다 크거나 같으면 인티그레이션의 수를 주파수에 따라 조정하는 단계, 상기 비교값에 따라 V(p,r)이 E(p-1,r)보다 작으면, 인티그레이션의 수를 표적전시시 표적의 끌림현상을 방지하기 위하여 미리 설정된 소정수로 정하는 단계, 및 거리셀 r 및 p번째의 펄스반복주기에서의 인티그레이션된 평균신호의 크기를 산출하는 단계를 구비하여 이루어지는 것을 특징으로 한다. 따라서 본 발명을 이용한 레이다 시스템은, 표적이 존재하지 않는 방위각에 대한 전시기에서의 표적 끌림현상을 방지하여 운용자의 혼란을 방지할 수 있으며 또는 S/N비를 향상시켜 미약한 신호에 대한 탐지확률을 높일 수 있다.The present invention relates to an integration method and an integration apparatus of a radar system. The integration method is an integration method for improving the S / N ratio of a radar system, wherein the signal value V (p, r) received from a current transmission pulse and an electric signal are transmitted. Comparing the feedback value E (p-1, r) of the integration result up to the pulse; if V (p, r) is greater than or equal to E (p-1, r) according to the comparison value, the number of integrations Adjusting the frequency according to the frequency, and if V (p, r) is smaller than E (p-1, r) according to the comparison value, the predetermined number is set in advance to prevent the target from dragging during the target display. Determining a number and calculating the magnitude of the integrated average signal at the distance r and the p-th pulse repetition period. Therefore, the radar system using the present invention can prevent operator's confusion by preventing target drag in the exhibitor with respect to the azimuth in which the target does not exist, or improve the S / N ratio to detect weak signals. Can increase.
