Analysis of NLFM Signals against the Doppler Effect and Background Noise| Chapter 1 | Techniques and Innovation in Engineering Research Vol. 2

 The study compares the Doppler effect and background noise to Nonlinear Frequency Modulated (NLFM)waveforms created using three-stage piecewise linear and two-stage piecewise linear and nonlinear functions. Various target speeds are used in simulations to examine the Doppler effect. For the investigation of background noise, additive White Gaussian noise is taken into account. In the current investigation, the NLFM developed utilising two piecewise linear frequency modulation outperformed other generated waveforms.

Study on Conventional vs. Convolutional Windows for Reduction of Side Lobes| Chapter 11 | Recent Developments in Engineering Research Vol. 12

 The goal of this study is to compare the performance of convolutional windows to that of traditional windows. Convolutional windows are created by convolving the window on its own. These new windows are used to generate a pseudo-LFM signal by combining two stages of piecewise linear frequency functions. The proposed LFM signal was simulated using both traditional and convolutional window functions, and convolutional windows produced higher peak to side lobe level ratio (PSLR) values than traditional windows.
