Blind velocity radar

WebJul 15, 2016 · The coherence and blind velocity are two important questions in multiple-input multiple-output (MIMO) radar ground moving target indication (GMTI). Multi-frequency signal is an effective way to solve the blind velocity problem, and multi-frequency signals are usually transmitted by MIMO radar. However, by this way the coherence is lost. This …

Intra-pulse scalloping is improved by shortening the transmit pulse or by modulating the transmit pulse. This can include frequency or phase shifting associated with pulse compression. Moving target indicator (MTI) radar reduces the impact of blind velocity by using redundant detectors that introduce a compensating reverse phase shift undoes the phase shift caused by Doppler from reflector motion. This is also improved by using 3 or more pulses with staggering …
