Abstract

Radiolocalization receiver with a massively parallel array of correlators, comprising a data compression module (199) to compress the incoherent integration values accumulated into the incoherent integration memories (176). By compressing incoherent integration values, relevant memory saving can be obtained or, in alternative, loss of data by excessive prescaling can be avoided or attenuated. The invention proposes a simple compression scheme based on offset subtraction which allows save memory size.
