Abstract: PURPOSE: A radar apparatus for measuring reflective characteristics of the earth surface and the sea surface and a measuring method using the same are provided to accurately measure the cross-sectional area, distance, relative velocity, beat frequency and doppler frequency and measure the reflective characteristics of the earth surface and the sea surface more accurately by generating an offset frequency in a transmission path, avoiding low frequency noise existing in the low frequency band and minimizing the phase noise, thereby implementing the advantages of FMCW(Frequency Modulated Continuous Wave) and the doppler radar. CONSTITUTION: A radar apparatus(10) for measuring reflective characteristics of the earth surface and the sea surface includes a transceiver(30), an intermediate frequency unit(40), a signal processing unit(50) and a signal process unit(100). The transceiver transmits a transmission signal through an antenna unit(20) by selectively performing frequency modulation and deviating the frequency as much as the offset frequency and receiving feedback signals reflected at a clutter through the antenna unit. The intermediate frequency unit(40) removes the noise by filtering for sensitive improvement of an output signal inputted from the transceiver and amplifies the output signal into a level which allows signal processing. The signal processing unit analyzes the beat frequency and doppler frequency through the signal processing of the output signal inputted from the intermediate frequency unit using FFT(Fast Fourier Transform). The signal process unit includes a control unit(60) receiving a calculation order of an operator, a calculating unit(70) performing necessary calculation according to the calculation order of the operator, an input and output unit(80) receiving the input of the calculation order of the operator and displaying the calculation result. The signal process unit receives the input of the output signals from the signal processing unit, calculates the radar cross-sectional area, provides the calculation result to the operator and relative velocity, and selectively performs frequency modulation by the operator.
