Claims

[Scope of utility model registration request]

A white noise generator that generates electromagnetic waves with a uniform spectral distribution over a wide frequency range, a bandpass filter that limits the frequency range of the white noise generated by this, and a bandpass filter that distributes this noise signal to each antenna element. an antenna array to convert noise signals into radio waves and radiate them, a spectrum analyzer to measure the frequency spectrum of radio waves reflected and received by a target, and the time from radio wave emission to reception. An azimuth and distance measuring device characterized by comprising a time measuring device for measuring.
