Technique for using biphase codes very high chirped.

摘要

A method (20) for use in a system of synthetic array radar, characterized by the steps of: transmitting (21) radar signals including a waveform SAR ultra-high resolution and high duty factor, generated using a biphase code with a high compression ratio predetermined pulse; applying the Fourier transform (25) to the response received radar, which includes a map SAR; multiplying (26) the Fourier transformed according SAR map by a stored set of complex weights; applying a low pass filter (27) to as Fourier transformed SAR map and compensated with complex weights to reduce the number of rank points; and applying the inverse Fourier transform (29, 31) to the compensated SAR map and after passing through the lowpass to get points compressed range corresponding to a SAR map having enhanced sensitivity filter.
