mm-wave radar - The new ECM-ECCM frontier

The present investigation is concerned with the relationship of mm-wave radar to electronic countermeasures (ECM)/electronic counter-countermeasures (ECCM). Electronic warfare support measures (ESM) are also considered, since employment of ECM against mm-wave radar places strong demands on ESM. The mm-waves are defined as wavelengths in the range from 1 to 10 mm corresponding to frequencies in the range from 300 to 30 GHz. Advantages of mm-waves over microwaves for radar applications are partly related to requirements for smaller antenna diameters, increased angular resolution/antenna diameter, increased bandwidth availability, increased range resolution, reduced vulnerability to unwanted detection by hostile forces, and smaller and lighter RF components.
