Abstract:

Research is concerned with two aspects of the design of a receiver which is employed for simultaneous reception of pulse and CW signals. The first deals with the gain characteristic of the RF preamplifier that is used. This gain characteristic must be uniform over the frequency pass band of interest in order to maintain maximum sensitivity. If the gain is not uniform, the sensitivity over the portions of the frequency pass band with lower gain will be degraded from the maximum capabilities of the components used. Examples of this degradation are given. Methods of detecting a CW signal are presented. To do this detection, a modulator must be inserted before the RF preamplifier. According to the modulation waveform of the CW signal, it is possible to use a narrow-band detection amplifier. Curves are presented which relate the unity SN sensitivities for pulse and CW reception. Author
