Signal compression aims to decrease transmission rate (increase storage capacity) by reducing the amount of data necessary to be transmitted. The discrete linear chirp transform (DLCT) is a joint frequency instantaneous-frequency transform that decomposes the signal in terms of linear chirps. The DLC...
openExample('signal/LinearChirpExample') is unidentified in version 2015. Help Shouldnt Matlab automatically 'see' the current version and translate automatically the command to avoid 2 hours of hassle??? 0 Comments Sign in to comment. Sign in to answer thi...
The linear chirp generator also includes a phase locked loop which is responsive to the output signal of the VCO and which has a reference frequency which is related to the repetition rate of the output signal of the VCO.doi:US5557241 APeter J. Burke...

If the frequency variation is constrained to change linearly over the pulse duration, then this chirped signal is termed as linear FM chirp one. It is further designated as an up-chirp or a down-chirp one depending on whether the carrier frequency increases or decreases over the pulse interval...
1) linear step-frequency signal 线性步进频信号 2) frequency-stepped chirp signal 线性调频步进信号 1. Thefrequency-stepped chirp signalis very common in ISAR imaging because of its peculiar characters. 线性调频步进信号由于其独特的优点更是在ISAR成像中占据了重要地位。
