Sub-nanosecond Pulse Generator for Through-the-Wall Radar Application
Original language description
This paper presents a sub-nanosecond pulse generator intended for a transmitter of through-the-wall radar. The basis of the generator is a step recovery diode, which is used to sharpen the slow rise time edge of an input driving waveform. A unique pulseshaping technique is then applied to form a Gaussian pulse. A simple transistor switching circuit was used to drive this pulser, which transforms a trigger signal to a driving pulse with the timing and amplitude parameters required by the step recovery diode. The maximum pulse repetition frequency of the generator is 20 MHz. High amplitude pulses are advantageous for obtaining a good radar range, especially when penetrating thick lossy walls. In order to increase the output power of the transmitter, theoutputs of two identical generators were connected in parallel. The measurement results are presented, which show waveforms of the generated Gaussian pulses approximately 180 ps in width and over 32 V in amplitude.
