摘要： The invention discloses a radar system (100) for the detection of low RCS-objects (110, 140, 150, 160, 190) such as forest fires, said system comprising a first plurality of stations (120) for transmitting radar energy, said stations having mechanically fixed antennas (220), and a second plurality of receive stations (130) for receiving reflections of radar energy transmitted from the transmit stations, said stations having mechanically fixed antennas (220). The antennas (220) of said transmit and receive stations have a main beam (221) which is essentially parallel to the ground, and at least a sub-set of the receive stations is equipped with means for recording a first and a second received signal, and means for subtracting one of said signals from the other of said signals. Said transmit and receive stations are arranged to function within the frequency range of 10-100 MHz.

摘要： The present invention relates to an electronic load module and to a method and a system therefor. The method comprises receiving control data (301) from a connectable power controller via a data bus connector (202), and controlling (302) an active load (203) based on the received control data to sink a defined current from a connectable device under test via a first input (204), The method further comprises controlling (303) the activate load (203) based on the received control data by means of a digital control circuit (201) and the connectable power controller to generate and maintain an ambient temperature of the device under test.
