... could have added a constant voltage to these waveforms; this can be done easily using the “dc offset” feature of the function generator. In that case the waveforms would have been shifted upward or downward by an amount equal to the DC offset. We would then modify Equation (1) by adding a constant t ...

... A. System Realization In general in pulsed-IV systems both Vgs and Vds pulsed biases are applied at the gate and the drain of a transistor. In the experiment reported here, a pulse is only applied at the drain and a constant DC voltage is used at the gate. It is assumed that slow memory effects are ...

Chirp compression



The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power. Furthermore, the process offers good range resolution because the half-power beam width of the compressed pulse is consistent with the system bandwidth.The basics of the method for radar applications were developed in the late 1940s and early 1950s, but it was not until 1960, following declassification of the subject matter, that a detailed article on the topic appeared the public domain. Thereafter, the number of published articles grew quickly, as demonstrated by the comprehensive selection of papers to be found in a compilation by Barton.Briefly, the basic pulse compression properties can be related as follows. For a chirp waveform that sweeps over a frequency range F1 to F2 in a time period T, the nominal bandwidth of the pulse is B, where B = F2 – F1, and the pulse has a time-bandwidth product of T×B . Following pulse compression, a narrow pulse of duration τ is obtained, where τ ≈ 1/B, together with a peak voltage amplification of √(T×B).
