Abstract: PURPOSE: An apparatus and a method of a digital cumulative spectrum analyzer for direction finding are provided to implement the characteristics of an input signal at angle through which a user can't monitor a display screen in real time in past time. CONSTITUTION: In an apparatus and a method of a digital cumulative spectrum analyzer for direction finding, an RF down-conversion unit(301) receives an RF signal from an antenna and converts it into a middle frequency. A digital processing unit(310) converts an analog signal which is obtained by covering the RF signal into a middle frequency into a digital signal. The digital processing unit reduces the sampling speed of the converted digital signal to covert a baseband complex number. A spectrum processing unit(320) maps angles corresponding to an azimuth and calculated level to an X-axis and an Y-axis and assign different color according to each accumulation ratio of a reservation mode.

Abstract: A direction-finding antenna using a phase comparison method is provided to operate five antenna elements more stably by providing a common reference ground plane to five antenna elements through an installation of a simple ground plate. A direction-finding antenna using a phase comparison method includes antenna arrays(101-105), transmission units(106,107) and a metal grounding part(108). The antenna array has a plurality of antenna elements which are vertically arranged on a circumference having a predetermined radius.
