10. An observation apparatus, comprising:
-
an observation signal processing unit; a physical quantity determining unit; a frequency determining unit; and a transmission signal processing unit comprising; a signal controlling unit, and a signal transmitting unit; wherein the observation signal processing unit receives an observation signal indicating a physical phenomenon occurring in the ocean or the atmosphere of an observation object sensed by a sensor apparatus, converts the observation signal into a digital signal, and adjusts an amplitude and a phase of the observation signal converted into a digital signal; wherein the physical quantity determining unit determines a physical quantity of the observation object by analyzing the adjusted phase and amplitude of the observation signal and the physical quantity includes at least a velocity and a density; wherein the frequency determining unit determines whether an observation frequency is to be changed based on the physical quantity of the observation object; wherein the signal controlling unit generates and adjusts a chirp signal corresponding to a periodical pulse signal radiated through a transmitting antenna; and wherein the signal transmitting unit transmits the chirp signal toward either the ocean or the atmosphere. - View Dependent Claims (11, 12, 13, 14, 15)
