  • Patent number: 8860605
    Abstract: A method for estimating the position and the speed of a target with a radar is provided. The radar emits a waveform including a train of pulses, each pulse having an OFDM chip constructed from subcarriers, the subcarriers covering the whole bandwidth of the radar. Upon receipt of the echoed pulses, some of the subcarriers are used in a step of Doppler processing, each of the subcarriers being fixed over the pulses. Upon receipt of the echoed pulses, other subcarriers, which are not used for Doppler processing, are used in a step of High Range Resolution processing, the subcarriers being randomly distributed over the pulses.

  • Patent number: 8159388
    Abstract: There is disclosed a method for filtering sea clutter in a radar echo using a hydrographic model. The method comprises the steps of determining parameter values of the hydrographic model using the radar echo, estimating the sea clutter corresponding to the sea surface as deduced from the hydrographic model and filtering of the estimated sea clutter from the radar echo.

  • Patent number: 6861977
    Abstract: This invention relates to radar signal processing. In particular, this invention concerns signal processing of agile Pulse Repetition Time (PRT) sampled signal transmitted using spread spectrum technique. This invention solves, in particular, the incompatibility between Doppler processing and spread spectrum such providing an improved anti-jamming technique without narrowing the Doppler range. The method for deconvolution comprises combining the pulses with the same carrier in a burst, transforming the obtained signals from time to frequency domain, and deconvolving the obtained spectra. In a first embodiment of this invention, such a deconvolution method is adapted to irregular PRT sampled signal comprises an irregular samples to regular zero-padded samples conversion step between the combination and the transformation steps.

  • Patent number: 6803876
    Abstract: This invention relates to radar signal processing. In particular, this invention concerns Doppler processing and clutter filtering on irregular Pulse Repetition Time (PRT) sampled signal. This invention solves the above-mentioned drawbacks, in particular solving the velocity ambiguity and filtering any type of clutter, providing a deconvolution method which filter any kind of clutter even varying clutter like sea clutter, rain clutter . . .
