Performance of MIMO radar using two-way music
Multiple Input Multiple Output (MIMO) concept have been a prevalent technology in the wireless communication system (IEEE 802.11n and 4G), as it helps to increase transmit power and data throughput by array gain and diversity gain, while reducing multipath fading. In recent years, the concept of...

| Summary: | Multiple Input Multiple Output (MIMO) concept have been a prevalent technology
in the wireless communication system (IEEE 802.11n and 4G), as it helps to increase transmit
power and data throughput by array gain and diversity gain, while reducing multipath fading.
In recent years, the concept of MIMO technology has been exploited for outdoor RADAR system
for direction finding of targets besides using the conventional mono-static and bi-static radar
system. Direction finding subspace algorithms such as MUSIC, ESPRIT have been often used
to estimate the angle of arrival (AOA) of signal path that has been transmitted from the single
element transmitters.
In this paper, we explore using the MUSIC algorithm for direction finding of the target in
the space for RADAR system equipped with antenna array at both transmitter and receiver.
This algorithm is known as Two-way MUSIC for MIMO RADAR system. We will assess the
performance of the Two-way MUSIC algorithm for MIMO RADAR such as the advantages and
limitations in terms of maximum number of target elements that can be detected for given number
of transmitters and receivers. We will also explore the optimum performance of the system for
different practical scenarios. |
