WebJan 1, 2013 · Abstract. A rectangular pulse-compression waveform having low-time side-lobes and zero mismatch loss is simulated. The waveform that is compressed with matched filter is continuous nonlinear frequency modulated (LFM), rectangular pulses. This is capable of achieving range side-lobe levels of better than−70 dB, suitable for use with satellite ...

WebDec 1, 2024 · Frequency modulation simulation schematic. In this schematic, the basic idea is to use the FM wave to modulate the current in the transistor. Here, I've used a common collector configuration with R_E as a current-limiting resistor. However, you could also use a common collector configuration (V_FM at the base) and measure the output across R_E. http://ecelabs.njit.edu/ece489v2/lab2.php
WebAn LFM pulse is one in which the "instantaneous frequency" changes linearly over the duration of the pulse. By "instantaneous frequency" I mean the rate of change of phase. Over its τ = 500 μ s duration, a pulse with "bandwidth" B = 50 k H z and center frequency f c = 150 k H z would be defined by. We can see that this sweeps from 2 π ( f c ...
