Conclusions

This paper aims at giving the present state of the Hudem project by describing the efforts and their results for increasing the knowledge on sensors and on sensor/ground characteristics, for designing new sensors or tuning old ones and for processing the data produced by sensors. Furthermore, it presents the detection as a global process wherein the outputs of the sensors, considered as skilled specialists, can be integrated in a fusion operation. The future work includes the further development of the sensor investigation and design, the enhancement of the signal preprocessing methods, the improvement of the dedicated expertise of each sensors and the development of associated effective data fusion methods. This implies as well trials in a multisensor environment which will be conducted in a near future.
