The participant was asked to bring the extremity to the
target angle again actively or to indicate when s/he reached the predetermined angle passively.
Using the double-pulse FDA approach proposed in [31], the
target angle can be estimated to be [[??].sub.s] = 0[degrees] by using the first pulse which can be seen as phased array, and then the target range can be estimated to be [[??].sub.s] = 50 km by taking advantage of the second pulse with FDA, as shown in Figure 5.
Long-range coverage provides accurate object discrimination, range and speed data, and
target angle for vehicles more than 100 meters away.
Now point the back of the unit to the target and use "capture" to enter
target angle in degrees.
Because 30 degrees AoB is the
target angle of bank for this pattern.

Target angle of subtracks in pitch-down mode.
In addition, we can assess the detection of the
target angle by varying the installation angle from -13[degrees] to 13[degrees].
The beat-signal is composed of the range, Doppler, and angle information of a target, where A is the signal amplitude, [f.sub.r] is the range beat frequency, [f.sub.d] is the Doppler-frequency, [theta] is the
target angle position, T is the PRI, d is the distance between receiving antennas, and [lambda] is the wavelength
