Abstract	PULSAR is an ultra wide-band radar developed to detect quickly buried mines on a large area. This paper presents briefly the recent development efforts on this system, especially on a new pulse generator (fast high voltage pulse generator) and a new UWB antenna (Dragonfly antenna). It also deals with the possibility to use several scissors antennas in order to build an antenna array. A study was carried out with 2 scissors antennas, one beside the other, in order to evaluate the influence of the distance between them. Other simulations are realised with only one generator connected to 3 antennas.
