The antenna(10) receives electric waves. The tuner(30), connected to the antenna(10), extracts a necessary frequency band. The frequency detector(40), connected to the antenna(10), detects a received unknown frequency. The narrow band converter(50), connected to the tuner(30) and the frequency detector(50), converts signals of the extracted band into narrow band digital IF(Intermediate Frequency) signals by using the detected frequency. The digital recorder(60), connected to the narrow band converter(50), stores the converted narrow band digital IF signals.

Abstract: PURPOSE: A direction detecting device is provided to improve a direction-detection accuracy by adding a weight to a portion where the accuracy is excellent. CONSTITUTION: A direction detecting device comprises a calculation block(610) which converts video signals of odd and even channels to measure maximum values of odd and even channels. A selector calculating part(620) receives the maximum values from the calculation block(610) to calculate a sector value. A channel compensating block(630) compensates the nonlinear characteristics with regard to an output signal of the calculation block(610) with reference to the sector value. An amplitude difference calculating block(640) calculates an amplitude difference of the odd channel and an amplitude difference of the even channel, and an amplitude difference of adjacent beams in response to an output signal of the block(630). A period direction calculating block(650) calculates period directions of the odd and even channels and of the adjacent beams. An intersection amplitude period direction calculating part(660) obtains a channel amplitude difference by comparing the period directions from the block(650) with a sector direction of the calculation part(620), and calculates a direction of a mixing amplitude period by adding a weight to a sector where a direction-detection accuracy is stable.
