For detection of objects around own vehicle, we consider an estimation system of target positions. In the use of parking assistance, wide observation area and high estimation accuracy are required. In order to realize the requirements, we focus on a radar network system which is constructed with multiple sensing devices. We proposed architectures of the wide emission by an array of transmitters, the improvement by using the directional emission and multipath signals.
