A new concept of transmitting antenna on bi-static radar for space debris monitoring

The aim of this article is to propose a new radar concept for the monitoring of space debris in order to increase the performance with respect to the traditional radars. Once put in operation, the new sensor will be able to improve the space surveillance and tracking services within the sensor network of the EUSST consortium. The architecture is based on past experience of observing space debris using the radar called BIRALES (BIstatic Radar for LEo Survey). The transmitting antenna that is described in this paper will be the new emitter of BIRALES. It is designed to be very flexible for any type of observations, modifying its parameters depending of the observation needs and according to the service to offer (monitoring of fragments, re-entry or for collision avoidance).
