WebThe blind ranges are given by rm = ( m c)/ (2 fn ), where rm is the blind range for a given value of m , m is a positive integer that indicates which of the blind ranges is being determined, c is the velocity of electromagnetic wave propagation in vacuum (approximately 3 × 10 8 m/s), f is the radar pulse repetition rate, and n is the ... The diagram below shows the characteristics of the transmitted signal in the time domain. Note that in this and in all the diagrams within this article, the x axis is exaggerated to make the explanation clearer. The carrier is an RF signal, typically of microwave frequencies, which is usually (but not always) modulated to allow the system to capture the required data. In simple ranging radars, the carrier …

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 … WebReturns from targets with corresponding velocities will be highly attenuated and cannot be detected by the radar. These velocities are called blind speeds. ... It will not detect high relative-velocity targets as well as can a high-prf pulse doppler radar, but it will detect low relative-velocity targets better because its low prf sees less ...

WebApr 4, 2024 · What is blind speed radar? radar blind speed: The magnitude of the radial component of velocity of an object, i.e., a target, relative to a radar site, that cannot be measured by the radar unit. Note: Radar blind speeds occur because of the relationship between the transmitted pulse repetition rate (PRR) and the received pulse-repetition rate.
