Ultra-wideband short-pulse radar with range accuracy for short range detection

DWPI Title: Ultra-wideband radar transmitter apparatus, has signal converter coupled to pulse generator and converting pulsed output signal into pulsed radar transmit signal with series of radar transmit pulses
Abstract: An ultra-wideband (UWB) radar transmitter apparatus comprises a pulse generator configured to produce from a sinusoidal input signal a pulsed output signal having a series of baseband pulses with a first pulse repetition frequency (PRF). The pulse generator includes a plurality of components that each have a nonlinear electrical reactance. A signal converter is coupled to the pulse generator and configured to convert the pulsed output signal into a pulsed radar transmit signal having a series of radar transmit pulses with a second PRF that is less than the first PRF.
Use: Ultra-wideband (UWB) radar transmitter apparatus.
Advantage: The apparatus supports detection of targets at short range over a wide range of velocities.
Novelty: The apparatus has a pulse generator producing a pulsed output signal with a series of baseband pulses with a first pulse repetition frequency (PRF). A signal converter is coupled to the pulse generator, and converts the pulsed output signal into a pulsed radar transmit signal with a series of radar transmit pulses with a second PRF that is less than the first PRF. The pulse generator is configured as a nonlinear transmission line (NLTL) pulse generator. A phase code modulator (16) is coupled between a local oscillator and a high frequency switch (12).
