A method for cost favorable determining a pulse response of a high-resolution band-limited radar channel

摘要

The pulse response evaluation method, for a high resolution, limited bandwidth radar channel, uses a channel estimator, with multiplication of the sampled reception signal (e) with an inverse estimation matrix, obtained by expanding the rectangular matrix provided by the components of the spread code to provide a quadratic matrix. The modified estimation of the radar pulse response is provided by a cyclic digital correlator for cyclic correlation of the reception signal with the elements of the inverse estimation matrix.
