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 ...

WebCreate a linear FM waveform with a duration of 0.1 milliseconds, a sweep bandwidth of 100 kHz, and a pulse repetition frequency of 5 kHz. Add noise to the linear FM pulse and filter the noisy signal using a matched filter. This example applies a matched filter with and without spectrum weighting. Specify the waveform. WebFrequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications , …
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. …
WebA simple and effective FM demodulation technique involves a high-pass filter (for FM-to-AM conversion) followed by an AM demodulator. A high-pass-filter-based FM demodulator is …
WebHere is the FM waveform (with m = 4) that we saw in the previous page: We can compute the PM waveform by using the following equation, where the signal added to the argument of the carrier wave uses positive sine (i.e., the original signal) instead of negative cosine (i.e., the integral of the original signal). bjf surveysWebNov 19, 2013 · The output FM signal has frequency deviation of \(\varDelta fs=50\,\mathrm{k}\mathrm{Hz}\). For the given data, 1. Calculate frequency swing of the carrier in this FM signal; 2. Determine the highest and the lowest frequencies attained by the modulated signal; and. 3.
