Abstract: The present invention relates to a method for frequency sharing of a high frequency ocean surface radar, which assigns two signal waveforms orthogonal to each other to the same frequency band so as to reuse the frequency, and an embodiment of the present invention is as follows. Two radars can be operated without interfering each other in the same frequency band by assigning an up-chirped linear frequency modulation (LFM) waveform signal and a down-chirped LFM waveform signal of the same frequency band to the two frequency ocean surface radar, respectively, using the characteristics of the two waveform signals orthogonal to each other. In addition, multiple radars located within the distance possible to be interrupted can be operated without interfering with each other by combining and assigning multiple frequency bands and the two orthogonal signals to the radars. Because the frequency reuse technique of the present invention continuously uses chirped LFM signals without time division, continuous real-time observation over a large region is possible and thereby the accuracy of obtained information on an ocean surface is raised. Efficient frequency reuse is achieved by combining two LFM signal waveforms, which have a characteristic of being orthogonal to each other, with multiple frequency bands.

Abstract: A conversion algorithm of the rainfall intensity distribution according to the accumulated time data is provided to effectively estimate domestic one minute accumulation rainfall intensity distribution by converting data measured for a long time more than one minute into the one minute accumulation rainfall intensity distribution. Rainfall intensity data which is measured by a specified few minutes unit is read out from a database(101). A first coefficient of correlation and a second coefficient of correlation which correspond to the specified few minutes unit are obtained to convert the rainfall intensity data into one minute accumulation rainfall intensity data(102). The measured rainfall intensity data are converted into the one minute rainfall intensity data by squaring the first coefficient correlation in the measured rainfall intensity data and multiplying the result by the second coefficient correlation(103).

Abstract: An apparatus and a method for receiving a signal by using an RF filter bank are provided to minimize the interference from the outside by using an RF filter bank placed at an RF front-end. An RF broadband filter(11) removes signals except the signals of the preset RF bandwidth among signals received at an antenna, and an RF filter bank(12) filters an RF signal, which passes through the RF wideband filter, by a frequency channel filter. A frequency down-converting unit(10) noise-amplifies the passing RF signal, and removes a harmonic signal which occurs during the amplification. The frequency down-converting unit mixes the RF signal with a local oscillating signal to convert the mixed signal into an IF signal.
