Latest Patents

Michel Poullain holds a patent for a "Device for eliminating low frequency noise from a transmission system." This invention specifically addresses the noise in 1/f from a Doppler radar. The device includes a phase coder in the high-frequency emitting system that introduces a phase shift of 0 and π alternately at a frequency of PRF/2. Additionally, the receiving system features a decoder or gain inverter that is programmable between -1 and +1. This component acts similarly to the coder on the receiving signal and includes a low-pass filter downstream from the decoder to eliminate the noise in 1/f that appears at PRF/2. The device is particularly applicable to ground surveying radar.
