A digital processor system for use with multi-band radar systems

Racal-Thorn, Wells (formerly Thorn EMI Electronics Limited) have been involved in radar signature measurements at Wells in Somerset. Since 1979 the Full-scale Trials Group (FST) have designed and developed mobile radar systems for full-scale dynamic measurements of military platforms in land, sea or air environments. The paper describes the digital processor systems (DPS) hardware designed and built by FST, with examples of the digital output waveforms, plus the received digital processing to record the compressed and uncompressed data. The examples also compare several waveforms which may be used in practical radar systems. The facilities offered by the DPS for radar applications are complimentary to the work in specialised ELINT technology which is also ongoing at Wells. The complex radar signals can be used to evaluate the performance and response of systems in live trials, including both ELINT and ECM sensors
