Abstract or Summary
  • This thesis discusses the design of an approximate matched filter capable of detecting a 30 MHz, 0.45 microsecond pulsed carrier in white noise. The theoretical background, which the matched filter is based upon, is presented. The matched filter described herein is composed of an open-end lumped-parameter delay line and a narrow-bandpass amplifier. Passive signal generation is employed by using the fact that the impulse response of a circuit is the inverse Fourier transform of the frequency response of the circuit. In this experiment, therefore, two identical circuits are used; one is for signal generation while the other is for the matched filter. The signal is not reproduced at the output of the matched filter, but the signal-to-noise ratio is maximized. The matched filter circuitry is compact and is economical to build. There are a few limitations which affect the response of the designed circuit, but they are not those that cannot be solved.
