ーダ装置。 In a synthetic aperture radar mounted on a flying object such as an artificial satellite, there is a transmitter that converts the chirp pulse signal, which is the transmission signal of the synthetic aperture radar, into a signal with a frequency different from that for the synthetic aperture radar, and a transmitter that converts this signal into a signal. A first antenna section that emits to the ground surface and receives the reflected radio waves; a first receiving section that receives the reflected radio waves through the first antenna section; and a synthetic aperture that analyzes the altitude information of the flying object based on the received signal. a controller that sets a pulse repetition frequency of a radar transmission pulse signal; and a second controller that emits the chirp pulse signal from the transmitter to the ground surface based on the set repetition frequency and receives the reflected radio waves.
A synthetic aperture radar comprising: an antenna section; and a second receiving section that receives the reflected radio waves through the second antenna section and outputs the received signal to a signal processing system as an output signal of the synthetic aperture radar. Device.
