摘要：

A new approach for local area weak signal detection is presented Sector spatial pre-filtering and image part high resolution algorithms were used in this method The steps are: firstly, received data of array is pre-filtered by sector spatial filter. Secondly, according to the character of the noise field filtered, image-part high resolution algorithm is used to scan the local area Then, the signals azimuths are estimated by the spectrum of signals. Computer simulation invited availability of this approach.
