摘要

The present invention relates to a rainfall radar system for improving observation performance of a rainfall radar, and a multi-pulse detection method for improving observation performance of a rainfall radar. A first aspect of the present invention is a radar apparatus comprising: a rainfall radar (10) for acquiring radio wave energy information of a pulse signal reflected by a rainbow (A) through transmission and reception of a radio wave with respect to a rain cloud (A) through a transmitting and receiving antenna; A pulse receiving point device 20 in the radio wave transmission direction of the rainfall radar 10; A pulse receiving point device 20 for receiving a signal for the rainfall radar 10 and for increasing the received signal level in order to improve the observation performance of the rainfall radar, A reception antenna and a low noise amplification frequency conversion unit 21 for receiving and amplifying the pulse frequency transmitted from the transmission antenna unit 22 and transmitting the pulse frequency to the transmission antenna unit 22; A signal for selecting one channel of a predetermined band among the signals included in the transmission pulse frequency range of the rainfall radar 10 and demodulating the demodulated signal and for transmitting the radar beam in the propagation direction toward the non- An antenna section 22; And an antenna controller (23) for acquiring propagation energy information of a pulse signal reflected by a non-cloud (A) through transmission and reception of radio waves to a non-cloud (A); The present invention provides a rainfall radar system for improving the observation performance of a rainfall radar system including a rainfall radar system. A second aspect of the present invention is a method for controlling a rainfall radar system in which a rainfall radar 10 obtains propagation energy information of a first pulse signal reflected by a rain cloud A through transmission / Stage 1; The pulse receiving point device 20 additionally disposed in the radio wave transmission direction in addition to the rainfall radar 10 transmits the radio wave for the rain cloud A using the transmitting antenna section 22 and the receiving antenna and the low noise amplification frequency conversion section 21 A second step of acquiring propagation energy information of a second pulse signal reflected by the rain cloud A using the first pulse signal; The present invention provides a multi-pulse detection method for improving the observation performance of a rainfall radar including a plurality of radar detectors. Thus, by receiving a signal in the long-distance transmission direction, the level of the received signal at a long distance is increased, thereby enhancing the identification of the property of the far-away iris and increasing the signal-to-noise ratio of the received signal. In addition, the present invention can remarkably improve the distance detection ability below the zero elevation angle, thereby providing an effect of expanding the detection range.
