A pulse compression system employing a linear FM Gaussian signal

Abstract: Some of the factors involved in the design of a radar pulse compression system are discussed. These include the compression ratio, the detailed characteristics of the signal, the sidelobe level of the receiver output waveform (signal autocorrelation function), the sensitivity of the sidelobe level to Doppler frequency shift in the signal, and the relative complexity of the equipment required to generate and receive the signal. A signal of Gaussian envelope and linear frequency modulation is shown to have an au… Show more

“…This is because ultrasound will suffer high attenuation [14][15][16] and various noises [17,18] during transmission, resulting in weak transmitted signal and poor signal-to-noise ratio. Hence, using effective methods [19][20][21] to overcome these limiting factors is the key to applying the air-coupled ultrasonic testing technique to the quality inspection of honeycomb sandwich composite materials.…”

“…The matched filter for this coded waveform was shown to be the complex conjugate of the transmitted signal. 4,5 Pulse compression can increase the signal-to-noise ratio (SNR) without deteriorating the range resolution, where its effectiveness depends on the time-bandwidth product of the transmitted waveform. Despite the unlimited variety of the input waveforms, they can all be classified according to the time-bandwidth prod-uct.…”
