Abstract

The paper focuses on adaptive spatial filtering of directional interference in a radar. In particular, the effects of the analogue to digital converters (ADCs) on the interference cancellation ratio (ICR) are analysed. The following error sources are taken into account: the limited number of bits, the limited dynamic of the radar receiver and the internal distortion and the offset introduced by the ADC device.
