A method of controlling a radar system by: receiving a radar return signal from a target and generating a range-Doppler target image signature of the target; selecting a spectral line within the range-Doppler target image signature from a modulation feature on the target which includes an effective point scatterer; providing a range profile for the spectral line; obtaining a reference range profile of a reference point scatterer; and determining a difference between a power at a range shorter than a peak corresponding to the modulation feature in the range profile and a power at a corresponding range of the reference range profile. The method may further include controlling provision of the range-Doppler target image signature based on the difference.

Controlling a radar system and the provision of a range-doppler target image signature

A method of controlling a radar system by receiving a radar return signal from a target and generating a range-Doppler target image signature of the target; selecting a spectral line within the range-Doppler target image signature from a modulation feature on the target which includes an effective point scatterer; providing a range profile for the spectral line; obtaining a reference range profile of a reference point scatterer; determining a difference between a power at a range shorter than a peak corresponding to the modulation feature in the range profile and a power at a corresponding range of the reference range profile; and generating a first control signal or a second control signal arranged to provide or prevent provision of the range-Doppler target image signature based on the difference.

A process for reducing erroneous plots when detecting targets using High Frequency surfacewave radar (HFSWR) is provided. Detection of genuine targets is thereby enhanced. A first difference in range of an apparent target is determined, based on range data, associated with the apparent target. A second difference in range of the apparent target is determined, based on Doppler data, associated with the apparent target. The first and second range differences are compared to one another over time to assess a consistency therebetween.
