Abstract :
Several methods are developed for detection of signals with known frequency characteristics, such as detection of chirp radar signals using matched filters. An innovative method of detecting broadband dispersive signals is proposed where the known characteristics of exponential frequency decay form the basis of detection. Computer simulations are performed on a known signal model with a frequency content of 40 to 200 MHz. Effective detection is demonstrated even in the presence of background random noise or a sinusoidal noise burst with a signal-to-noise ratio (SNR) of -2 dB. Techniques are suggested for analog or digital implementation of the various process steps, with emphasis on radio frequency (RF) requirements.<>
