Other high-resolution techniques
The high-resolution techniques presented in this chapter can be considered to be extensions of the main target recognition methods discussed earlier in the book. The super resolution and monopulse techniques effectively improve the resolution of radar measurements by utilising relatively high signal-to-noise ratios. However, for the practical implementation of these methods, the radar must operate at higher than normal sensitivities, which means that the target range is short or there is time available for long integration periods. The polarisation techniques are directly compatible with, and would be used in conjunction with, other high-resolution methods. Relatively high signal-to-noise ratios are required to extract all the polarisation matrix components. The impulse and ultra-wideband techniques are extensions of high-range resolution methods and tend to have niche applications. The combined high-range resolution and high-frequency resolution techniques are based on the respective individual techniques and can be applied to targets with mechanical propulsion systems. Components such as rotors, rotor blades and jet engines can be detected, recognised and localise in range, to supplement range profile data.
