The radar end-users are demanding more and more of their systems, while the targets are designed to have an as small as possible RCS, which makes them more difficult to detect. With multiple transmitters and receivers it may be possible meet the stringent demands of the users. Extending monostatic radar functions like target localization and Doppler velocity estimation to a multistatic configuration will show some significant improvements in resolution and overall situational awareness. With multistatic target localization, the cross-range resolution can be greatly improved and the overall system is much less susceptible to dips in the RCS, because it sees the target from different angles. With multistatic Doppler velocity estimations, a complete 2D or 3D target velocity vector can be composed to aid tracking and imaging techniques like ISAR. Multistatic ISAR is a perfect example of the strength of combining multiple radars. It can be used to achieve a higher resolution for the same integration time as a monostatic radar, or it allows a reduction of integration time, with a resolution equal to the monostatic case. A new concept in multistatic ISAR is the interpolation of the ISAR data. In case the geometry between the target and the radars does not meet the requirements for coherent combining the images, an interpolation of the data can be done. Not only the geometrical requirements can be eased, also the integration time can be artificially increased, allowing the radars to spend more time on other functions. Another new approach to multistatic ISAR is the incoherent combination of multiple ISAR images. This concept is called 2D ISAR and allows the creation of high resolution images with low resolution surveillance and MTI radars. The main idea of 2D ISAR is seeing the target under different angles, so the amplitude of the summation of scatters will be higher than that of the sidelobes, which allows to estimate the overall target dimensions.
