New chirp sequence radar waveform

Autonomous radar pulse modulation classification using modulation components analysis

“…The simulation adopts modulations in Table 2. The three kinds of hybrid modulations are the LFM-BFC modulation [10] in the DFC family and the LFM-BPC [8,9] and the BPC-BFC [11] modulations in the DPC family. Figure 7 gives the probabilities of successful modulation family recognition (PSMFRs) for the simulated IMOPs.…”

“…The newly emerging radar systems, such as the cognitive radar [4], the waveform-agile radar [5], and the multiple-input multiple-output (MIMO) radar [6,7], are changing their operation modes and bringing waveforms with various kinds of complicated IMOPs. Apart from that, some waveforms with hybrid IMOPs, such as the discrete phase codes on linear frequency modulation (LFM) [8,9], multiple frequency-shift keying (FSK) waveform outperformed by a chirp modulation [10], and the combination of FSK and phase-shift keying (PSK) modulations [11], have also been reported. These complicated and hybrid IMOPs are posing a particular threat to modern EW intercept receivers.…”

Fast chirp FMCW Radar in automotive applications

“…This needs a second dimension FFT. More detailed signal processing procedure may be referenced from [11][12][13].…”

The design and implementation of automotive radar system based on MFSK waveform

“…However, the complex range and velocity matching algorithm greatly increase the amount of calculation. Paper [6] proposed a period-varying sawtooth wave measurement method, but the method with minimum coupling range difference may loss the target with large Doppler shift and generate ghost targets. An adaptive beam-controlled phased array radar is designed to improve the measuring distance and precision, but the complicated hardware structure and high cost limit its application [7,8,9].…”
