We propose a double-modulated frequency modulation waveform for multiple-input multiple-output radars. The transmitted waveforms are divided into two segments with the same bandwidth and different durations. The durations of all the segments among different waveforms are used to optimize the performance....
Focuses on the electronic circuit that uses a phase-detector signals of a precision waveform-generator integrated to perform frequency modulation and demodulation. Production of a duty-cycle-modulated train of rectangular current pulses using a phase-detector output; Use of an external comparator for ...
Phase modulation is used to reject ambiguous targets while frequency modulation is used to achieve the finest resolution. Convolution of the phase modulated and frequency modulated waveforms yields a waveform which has the fine resolution property of the frequency modulated signal and the ambiguous ...
