Development of a Small Phased Array SAR-MTI System for Tactical UAV

Autor: Rossum, W.L. van, Grooters, R., Halsema, D. van, Lorga, J.F.M., Otten, M.P.G., Vermeulen, B.C.B., Vlothuizen, W.J.

Publikováno v: Advanced Sensor Payloads for UAV; Paper presented at RTO Sensors and Electroncs Technology (SET) Symposium in, Lisbon, Portugal on 2-3 May 2005, 23/1-23/12

A small SAR-MTI system is being developed at TNO, aimed at deployment on tactical UAV, such as the SPERWER, in use with the Royal Netherlands Army. The system makes use of modern front-end technology, to provide flexible SAR imaging and MTI modes. Ma

Ripple+slope performance of satellite channel amplifiers related to GaAs MMIC technology

Autor: Henkus, J.C., Grooters, R.

Publikováno v: Henkus, J.C. ; Grooters, R. (1994) Ripple+slope performance of satellite channel amplifiers related to GaAs MMIC technology. In: Gallium Arsenide Applications Symposium. GAAS 1994, 28-30 April 1994, Turin, Italy.

This paper reports on the development of two generic satellite transponder channel amplifier subsystems for the 5.35-5.65 GHz band, respectively the 10.70-12,75 GHz band, both to be based on full application of GaAs MMIC technology. A novel Slope Com
