The design of a coherent, frequency agile 94 Ghz radar frontend is reported. This radar includes features like pulse to pulse frequency agility in steps of 10 MHz within a bandwidth of 400 MHz and fixed or staggered PRF in a wide range between 1 and 50 kHz. The output power of 16 Watt and the antenna gain of 45 dB result in an effective radiated power of 89 dBm. The polarisation of the transmitted wave is switchable from pulse to pulse either from RHC to LHC or from horizontal to vertical. This depends on the kind of primary feed horn used for the 300 MM cassegrain antenna. Co- and cross polarized echo signals are received and processed by two separate but identical receiver channels. Line scanning with a rate of 20 scans per second is done by a flat rotating mirror.
