CONSTITUTION: A target decision device (100) using radar comprises a bit signal generator (110), a bit frequency extractor (120), and a determining unit (140). The bit signal generator produces a bit signal using a radar transmission signal and a radar reception signal for one or more targets.

The determining unit determines whether the target is the same target or not using the similarity between power spectrum densities of the up-bit frequency and the down-bit frequency. A target position calculation unit calculates the position of the target in a frequency cell section in which the similarity between power spectrum densities of the up-bit frequency and the down-bit frequency is higher than a reference similarity value.

Abstract: PURPOSE: A pulse radar receiving device and a method for detecting pulse radar are provided to efficiently use a memory size which is necessary by reducing counting amount which is necessary for extracting the distance and speed of a detection object. CONSTITUTION: A pulse radar receiving device(100) comprises a switch(105), a memory(110), an FFT processing unit(120), and a distance velocity extracting unit(130). The switch transfers one distance gate about each sample. The memory assigns pulse within a pulse repetition interval to the distance gate in a column direction. The FFT processing unit frequency-changes pulse data which is saved in the memory to the column direction. The distance velocity extracting unit measures phase change which is changed by a target object at pulse repetition interval and estimates the speed of the target object.
