  • Patent number: 10298122
    Abstract: A switching mode DC/DC power converter for delivering a direct current to a pulse radar unit. A first switching element connects and disconnects the power converter from a power source in each cycle of the power converter. An inductor charges and discharges in each cycle. A capacitor maintains a DC output voltage as the inductor charges and discharges in each cycle. A second switching element transfers energy from the inductor to the capacitor when the first switch disconnects the switching mode power converter from the power source. A control loop regulates the voltage with a time constant, to a predetermined value by controlling the first switching element. An on time for the first switching element in each cycle is chosen to allow the current through the inductor to fall to zero in each cycle. The cycle is shorter than RF pulse duration and time constant of the control loop is longer than the RF pulses.

  • Publication number: 20180267163
    Abstract: A method and a device for detecting at least one target in an image, wherein the image comprises a set of pixels with a magnitude assigned to each pixel is provided. The method comprises an iterative process until the K+1th target does not show a probability increase above a predetermined threshold value. The method is performed by creating a candidate free image, calculating, for the candidate free image, the probability of there being a target at each pixel, by using Bayes theorem, determining a location of the candidate target K+1 in the image, determining the probability that there is a target at the determined location, by determining the calculated probability of there being a target at the determined location. By performing the above, the most probable locations for targets in the image are located together with the probability that the location holds a true target.
