Using the Digital Target Simulator

Use the digital target simulator with Ascope to simulate weather and clutter targets in the host workstation.

The digital target simulator can simulate up to 4 point targets. You can set the parameters of each target independently.

Select Options > Target Simulator.

The simulator and its control panel start.

Cx

Select Cx to indicate that the target impacts the data from the cross-polarization Rx channel (vertical polarity).

Co

Select Co to indicate that the target impacts the data from the co-polarization Rx channel (horizontal polarity).

Range (km)

How many km it will affect after the starting range

Length (km)

How far away from the radar the object is.

In the example plot, this is shown in the trapezoid changes. A range of 50 and a length of 10 km indicates the target occupies the range bins between 50 ... 60 km.

Power (dB)

Signal power of the target.

Gradient

How much the power changes over the range of the target.

For example, a Targ-1 target between 50 ... 60 km with the Power of 10 and the Gradient of -13 dB starts at the signal power of 10 dB @ 50 km and then drops 13 dB down to -3 dB at 60 km.

Doppler (Hz)

Doppler frequency of the target in Hz.

Gradient

How much the frequency changes over the range of the target.
