Assessment of a Millimeter-Wave Antenna System for MIMO Radar Applications

Optimization of a MIMO radar antenna system for automotive applications

“…5. A detailed description of the measurement setup and procedure can be found in [8] and it is here omitted to avoid duplications.…”

“…3 due to the complexity of the model, only one transmitter-receiver pair has been simulated; then it has been assumed that these results are valid for all the pairs. Considering that in [8] it has been proved that when identical antennas are employed, the properties of the AF depends only on the geometrical displacement of the arrays and not on their radiation pattern, it is unnecessary to use the full-wave simulation results for the calculation of the AF, since the same results as the isotropic case are expected.…”

“…The signal model that is used in this work is similar to what is presented in [8]. The system is composed of M t transmitting and M r receiving antenna arrays arranged on a one-dimensional lattice, as depicted in Fig.…”

“…Many papers have discussed possible strategies for the optimal antenna placement in MIMO radars, like for instance [5] and [7]. How- ever, a previous work [8] showed that the antenna positions and characteristics influence different system metrics, for example the achievable unambiguous range in the direction of arrival (DoA) estimation. Therefore, the search of the optimal antenna positions must take into account the specific application and the desired system requirements.…”

A 2D Method For Acquiring The Radiation Pattern Of Two-Identical Vivaldi Antennas By Using A Stepped-Frequency Continue Wave (SFCW) Radar And A Rotation Stage

“…For certain applications and under specific conditions, the information about certain parameters of an antenna are required, such as the radiation pattern at certain frequency or frequency range. Depending on the approach and the method applied, it might result in a complex and expensive task, as high-end equipment is required [1] and in occasions an anechoic chamber too [2] [3]. In cases where an anechoic chamber is not available, the measurements can take place in open spaces [4].…”
