Abstract


Orthogonal interpolation and pulse compression radar signal used front-end processing algorithm . Orthogonal complex signal can be obtained by orthogonal interpolation , which can easily get to the instantaneous amplitude of the signal , the instantaneous phase , and instantaneous frequency . Pulse compression technology , the large bandwidth product signal can be obtained high-resolution , to solve the contradiction between the detection and resolution of the radar . This paper analyzes the FIR filter design principles and design methods , and discussion of several common design method of orthogonal interpolation filter compression algorithm based on the full pulse pressure coefficients and pulse of two parts based on part of the pulse pressure coefficient ; theoretical analysis pulse pressure results , and discuss its practical significance ; frequency chirp signal itself when coupling phenomenon and its pulse pressure waveform is proposed based on the positive and negative slope of the chirp signal a new velocimetry .
