Abstract
An optimal position analysis unit 24 specifies an optimal installation position for a photodetector 6 by using spectra which by a spectrum and wind speed computing unit 23 calculated by analyzing output data of a photodetector 6 installed at different installation positions, controls a position adjustment made by an optical unit adjustment driving unit 7, and optimizes the installation position of the photodetector 6.
Claims17
A radar device comprising:
- an optical oscillator that oscillates light;
- an optical system that emits the light oscillated by said optical oscillator into atmospheric air and also receives said light which is reflected by an observation object existing in the atmospheric air and returns thereto;
- a photodetector that detects the light received by said optical system and outputs data showing a signal intensity of the detected light;
- a spectrum and speed calculator that calculates a spectrum by analyzing the data outputted from said photodetector, and also calculates both a speed of said observation object and a signal to noise ratio for each distance to said observation object from said spectrum;
- an optical condition adjuster that adjusts an optical condition of either said photodetector or said optical system;
- and
- an optical condition optimizer that determines said optical condition from a distance where said signal to noise ratio calculated by said spectrum and speed calculator crosses a threshold again after exceeding said threshold.
