Abstract
This paper presents the first measurement results of a new Orthogonal Frequency Division Multiplexing (OFDM) Multiple Input Multiple Output (MIMO) Radar prototype. It is designed to be operated in a dynamic multi-user environment where the individual sensor's RF bandwidth is very limited. Here, the radar uses only 30 MHz. The targeted applications are in the field of Urban (Air) Mobility (UAM) with a medium-range coverage up to 250 m. Another requirement is to observe a wide field of view in azimuth of about 100 degree with a high resolution in azimuth. This was implemented by using a 2 × 8 MIMO processing. A 20 ms frame based evaluation of the OFDM symbols allows to obtain a very high velocity resolution of below 1 m/s. This paper explains details about the radar system, the waveform and the processing but the main part of the paper focuses on the evaluation of a dynamic measurement.
