Abstract:
1. A pulsed compression noise correlation radar target detection apparatus, comprising: a wide sense stationary Gaussian noise signal generator generates a Gaussian noise signal and a normally distributed probability density function; a means for generating a pulse train combines said Gaussian noise signal with a linear frequency modulated noise waveform, generates a pulse train modulating said Gaussian noise signal and provides a pulsed linear frequency modulated fused noise waveform x(t) to a means for sensing targets; said target sensing means sends a signal to a target and generates a range and radar cross section of targets; a frequency demodulator detects a received signal r(t) from said target; said frequency demodulator, having a means for calculations, calculates a time dilation effect induced by target scintillation and generates a time dilated received signal r(t) that includes said time dilation effect; said frequency demodulator sends said time dilated received signal r(t) to a means for correlation mixing; said correlation mixing means integrates a product over time of said pulsed linear frequency modulated fused noise waveform x(t) and a conjugate of said time dilated received signal r(t) to provide an auto-correlated signal R a Fast Fourier Transformer converts said auto-correlated signal R
