Circuits and methods for generating a pulse are provided. The generating can comprise receiving at least one trigger input signal with a pulse generating circuit; generating a voltage pulse having a duration less than the avalanche time of a transistor in response to at least a portion of the at least one trigger input signal with the pulse generating circuit; transmitting the voltage pulse from the pulse generating circuit to a terminal of the transistor, the transistor constructed and arranged to be operable in an avalanche mode; and outputting an avalanche pulse from at least one terminal of the transistor in response to the voltage pulse. In some embodiments, the pulse can be transmitted with an antenna in a radar system, and a return pulse can be received and processed.

Avalanche pulser

A ground penetrating radar system is described that is able to create both low frequency, wide pulses, and high frequency, narrow pulses, to enable both deep and shallow operation of the ground penetrating radar on demand, including simultaneous operation.

Adjustable pulse width ground penetrating radar

A system for processing a signal comprises a transmit unit to transmit a signal, and a receive unit receiving the signal and performing equivalent time sampling thereon by sampling each cycle of the received signal and reconstructing the received signal from the samples, wherein the receive unit applies a plurality of down-conversion rates to the equivalent time sampling for an acquisition window.
