Provided are a system and method for processing a radar signal for deriving a Doppler frequency from a sampled digital input signal radiated by a frequency modulation continuous wave (FMCW) radar. The system includes a transmission module that repeatedly transmits a radar signal having a unique frequency variation and a pulse repetition interval, a variation module that varies the frequency variation or pulse repetition interval of the radar signal transmitted by the transmission module, an extraction module that, upon occurrence of interference between the radar signal having the varied frequency variation or pulse repetition interval and another radar signal, extracts an interference signal from the varied radar signal, and an adjustment module that adjusts the radar signal to reduce the extracted interference signal.

A method of controlling a radar alignment apparatus includes calculating a first target information by using a first radar and a second target information by using a second radar spaced apart from the first radar on a vehicle by a predetermined interval. The method includes determining whether the first target and the second target are a same target based on comparing at least some of the first target information with the second target, and determining whether misalignment exists in at least one of the first radar and the second radar based on a comparison of a first angle included a first target information with a second angle included in a second target information, correcting the misalignment by using the first target information and the second target information when it is determined that the misalignment exists in at least one of the first radar and the second radar.

The present invention relates to a biodegradable microbead having improved adsorptive power to anticancer drugs, to a method for preparing same, and to a method for treating cancer using same. According to the present invention, a rigid bead having excellent adsorptive power to anticancer drugs can be prepared through cross-linking and an amide bond between an albumin and an anionic polymer. Also, the microbead of the present invention is prepared by a biocompatible and biodegradable polymer so as to be safe when applied to the human body. Further, the microbead of the present invention can effectively inhibit the growth of a tumor by effectively blocking a blood vessel which supplies nutrients to a liver tumor, while continuously releasing anticancer drugs which are adsorbed into the surface of the bead. Thus, the present invention can be usefully applied to a chemoembolization of liver cancer.

Embodiments of the present invention may provide a method of preparing biodegradable polyester polymer materials both in a filament type and a sheet type using a compressed gas. The method of the present invention comprises the following steps: 1) preparing biodegradable polyester polymers through a solution-state polymerization process of a cyclic monomer using a compressed gas as a reaction solvent in the presence of a catalyst; 2) performing a flash-spinning process of the biodegradable polyester polymers prepared above to form a polymer material in a filament type; and 3) performing a calendering process of the polymer material in a filament type prepared above to form a polymer material in a point-bonded sheet type. Since the method according to the embodiments of the present invention has several advantages in that it employs compressed gas as a reaction solvent, which does not require the addition of a stabilizer and the solution-state polymerization, flash-spinning and callendering processes are conducted in a single consecutive process. This can be effectively used in the manufacture of biodegradable polyester polymer materials, which can be used as a biodegradable and biocompatible material useful in the fields of medicine, chemistry, agriculture, environment and the like.
