MXI-e1000

The MXI-e1000 is a Multichannel imaging radar with Inverse Synthetic Aperture radar (ISAR) imaging and three dimensional (3D) target reconstruction capabilities. The radar front-end is an X-band direct deramping Linear Frequency Modulated Continuous Waveform radar architecture. The radar front-end specifications are summarized as follow:

The antenna system consists of one transmitting and three receiving elements. This configuration allows for the interferometric approach to be used for 3D imaging. In any case, this multichannel
configuration can be exploited for other purposes.

In order to achieve a compromise between the coverage and the gain of the antennas, both the transmitting and receiving antennas are characterized by a half power beamwidth of 60° in azimuth
and 20° in elevation, and a maximum gain of 13 dBi. The embedded ventilation system ensures a proper thermal dissipation guaranteeing the IP55 enclosure protection.

The MXI-e1000 has the following features:

  • light weight
  • small size
  • easy deployable
  • low power consumption
  • very low electromagnetic transmission
  • deployable in a radar sensor network

All the above characteristics makes the MXI-e1000 easily installable in all weather, day/night conditions and close to civilian buildings and structures.

The multi-channel configuration enables the application of the 3D target reconstruction processing. In particular, this method exploits interferometric ISAR imaging (InISAR) to estimate the heights of the dominant scatterers.
