TNO-FEL is developing a miniature, lightweight, low cost, and scalable SAR/MTI system called 'MiniSAR'. The MiniSAR system will be unique in its size and architecture. Initially the demonstrator system will be integrated in a two-seater motorglider platform. Wherever possible, commercial-off-the-shelf (COTS) products are being used. This paper...

There is an increasing interest in low-cost, high-resolution imaging radar systems to be operated from small and maybe even unmanned platforms. Existing imaging systems are generally too heavy for small platforms, or too expensive in day-to-day use to be applied in small-scale civil applications. Combining the compactness of FM-CW radar systems...

For small-scale earth observation applications, there ia a special interest in low-cost, high-resolution imaging radars small, enough to be operated from small, possibly unmanned aircraft. The combination of FM-CW technology and the high resolution of SAR systems should result in such a small, cost-effective imaging radar. In a new project the...

In this project we study radar scattering from the sea surface in a number of ways. We generate 3D realisations of the sea surface and models of breaking waves. These objecs are put in CAD format. A ray tracing algorithm is used to calculate the illumination of the object and the local incidence angle of the radiation. Based on these results a...

Synthetic Aperture Rada¬° can be an important tool for operational forest mapping and monitoring in the tropics. In the development toward large scale operational use of SAR, however, a number of issues must still be resolved, pertaining to the performance and economics of SAR sensors in tropical forest management applications. The fully...

After the completion of the PHARUS polarimetric phased array SAR, an extensive prograrnme of data acquisition was carried out under the PHARUS Familiarisation Programme, a project for the National Remote Sensing Board (BCRS). The Familiarisation Programme has been aimed at the acquisition of PHARUS data to demonstrate the potential of the PHARUS...

We have studied remote sensing data from sensors in different wavelength regions (optical, thermal infrared and microwave) and from different platforms (airborne and spaceborne) in order to extract geographical information. By comparing the extracted information with an existing geographical database ofa test area in the Netherlands we find that...

PHARUS is a Dutch phased anray SAR system with an active (Polarimetric) antenna. The antenna consists of 2 rows of 24 transmit/receive modules; the amplitude and phase of each of these can be fully controlled from pulse-to-pulse. This allows very flexible beam steering capabilities. Some experiments were carried out using the electronic beam...

The use of distributed power in a, on a phased array antenna based, SAR system offers new possibilities for the system operation. As a preparation for future spaceborne SAR systems using solid state transmitters with electronically steerable phased array antenna, the PHARUS system has been constructed. The system is installed on a Cessna...

PHARUS is an airborne fully polarimetric C band SAR. It uses a compact phased array antenna with electronic beam steering. Its design provides for a flexible and robust system concept, suited for operational use on small aircraft. PHARUS was developed in The Netherlands to cater for both the military and civil markets. Its development was...

The PHARUS system is an example of a high resolution aircraft SAR sensor. Specially the PHARUS system, due to the flexibility of the operating modes, is a candidate to be used complementary with present and planned spacebome systems. The system can also be used as a demonstration system for future spacebome systems such as ESA's AS AR. This...

Synthetic Aperture Radar (SAR) is today a valuable source of remote sensing information. SAR is a side-looking imaging radar and operates from airborne and spacebome platforms. Coverage, resolution and image quality are strongly influenced by the platform. SAR processing can be performed on standard computers or dedicated hardware architectures,...

Groundbased scatterometry in The Netherlands has proven to be essential in studying the scattering of microwaves by vegetation and sea. The results of groundbased measurements were among others used for the development of suitable models and for the design of a digital and calibrated airborne X-band SLAR system. Among others the multitemporal...
