the detection unit is configured to measure a received high frequency signal (S) reflected or transmitted by an object, and to provide measurement tuples (T), each measurement tuple (T) including a high frequency signal amplitude (A) of the measured high frequency signal (S) and at least two-space coordinates of the object reflecting or transmitting the measured high frequency signal (S); and
the coding unit is configured to encode the high frequency signal amplitudes (A) of each of the measurement tuples (T) provided by said detection unit, wherein the coding unit is configured to encode the high frequency signal amplitude (A) of each of the provided measurement tuples (T) as a corresponding image point density, the coding unit comprising an output unit adapted to output the measurement tuples (T) with the encoded high frequency signal amplitudes (A),
wherein said output unit comprises a display configured to display the measurement tuples (T) with the encoded high frequency signal amplitudes (A) of a high resolution screen comprising a plurality of image pixels, wherein distances between active illuminating image pixels of said high resolution screen are controlled by a display control unit of said output unit in response to the encoded image point densities provided by said coding unit, and

wherein said coding unit is configured to encode the high frequency signal amplitudes (A) of the measured high frequency signal (S) as a number of active illuminating image pixels per display area of said high resolution screen of said display, and

2. The measurement apparatus according to claim 1 , wherein said coding unit is configured to encode the high frequency signal amplitude (A) of the measured high frequency signal (S) in a normal display operation mode by increasing proportionally or logarithmically the number of active illuminating image pixels per display area of said high resolution screen of said display with an increasing value of said high frequency signal amplitude.

3. The measurement apparatus according to claim 2 , wherein said coding unit is configured to encode the high frequency signal amplitude (A) of the measured high frequency signal (S) in an inverted display operation mode by reducing proportionally or logarithmically the number of active illuminating image pixels per display area of said high resolution screen of the display of said output unit with an increasing value of said high frequency signal amplitude (A).
