RIASSUNTO

A study of the potentials of Global Positioning System (GPS) satellites as passive radar illuminators for ground target detection is presented. GPS signals are promising due to their global coverage and the availability of multiple satellites wherever over the world. The main drawback is the low power at ground level that limits system coverage. For coherent processing, the Cross Ambiguity Function (CAF) is generated using reconstructed reference signals. Signal to noise ratio can be increased by coherent integration in the CAF domain. This approach has been studied for commercial air-planes and ships of different sizes (from ferries to fishing boats). In this paper, the detection of cars in a semi-urban environment is considered. The demonstrator IDEPAR was updated for GPS reception using commercial hemispherical GPS antennas. During the measurement campaign, a cooperative target was employed for validation purposes. Results confirmed the system capabilities for ground target detection in low range conditions. These first results are a probe of concept and motivate the design of directive GPS surveillance antennas and multistatic processing for improving the achievable coverages.
