We use the proposed method and the old imaging method  to handle the echoes from the point target
P5 in the spotlight mode of the receiver, respectively.
In this study, actuator-assisted calibration was implemented on three point-based phantoms: (1) single cross wire phantom, (2) original collinear point target
phantom, and (3) modified collinear point target
Figure 2 shows the range migration phenomena of a strong point target
in the range-Doppler domain.
The closest slant range from the platform to the point target
P([r.sub.0], [x.sub.0]) is [r.sub.0].
In bistatic SAR, assuming that radar transmits a linear frequency modulated (LFM) signal with chirp rate k and center frequency [f.sub.c], the echo from a single point target
can be expressed as
Maximum effective range: Area target: 800 meters; point target
: 1,800 meters with tripod.
Range: 300 meters max effective range for point target
The launchers give military and law enforcement officers the ability to deliver less-lethal rounds accurately to a point target
at 50 meters.
'It wasn't pretty but this result will boost our confidence,' said Wilkinson, 'If we can take six points from our games against Cheltenham and Notts County we could be well on the way to our 50 point target
They achieved their coaches' aims by reaching their try bonus point target
as early as the 27th minute.
'Latest forecasts continue to indicate that average inflation is likely to settle slightly below the 3 percent, plus or minus 1-percentage point target
range in 2016 and rise toward the mid-point of the target range in 2017 and 2018.'
Latest forecasts indicate that average inflation is likely to settle near the lower edge of the 3.0 percent +- 1.0 percentage point target
range in 2016 and rise toward the mid-point of the target range in 2017 and 2018.
