Investigation of Noise Immunity of Ultrawideband Pulse Radar Sensors on the Base of Single Chip

The principles of evaluating the noise immunity of ultrawideband pulse radars based on single-chip XeThru-Novelda transceivers are considered. A mathematical description of the method for reconstructing the signal shape from its mixture with jamming is given based on the analysis of the gated sampling algorithm in the XeThru-Novelda microcircuit. Functional diagram of a single-chip transceiver as part of the UWB pulse radar sensor and the scheme of the threshold level quantizer were developed. The result of reconstructing the pulse signal from its mixture with harmonic interference for different number of accumulated pulses is shown. The efficiency of the algorithm for synchronous accumulation of a large number of ultrashort pulses under the influence of a jamming signal to increase the signal-to-noise ratio is shown.
