Phased.Rad​arBackScat​teringTarg​et be used in bistatic configuration

Can Phased.RadarBackScatteringTarget be used in bistatic scenario? Or how can we model angle-dependent RCS for a bistatic configuration?

Bistatic and monostatic RCS is a bit different in the sense that bistatic RCS not only depends on the incident angle, but also depends on the departing angle. If the difference between the two angles are small, you can use the monostatic RCS to approximate the bistatic RCS.

What is your use case for modeling bistatic RCS? Do you have a measurement that you want to incorporate into the object? If so would it be possible to share the format of the measurement?

Hi Honglei,

I am looking to model a target with varying RCS with respect to each aspect angle and construct a bistatic radar to capture the target.

The measurement I want to incorporate is to give a different RCS value for different azimuth and elevation angles. Hence, could you help me with what RadarTarget Object I could use to incorporate this?

[Honglei Chen]

At this point the target objects in the toolbox doesn't help much. phased.RadarTarget does have a bistaitc mode but that one only applies when you model polarization. In other words, it assumes the RCS of the target is constant but the angles are used to determine polarization loss.

The easiest thing to do, if you have data, is to build a look up table using custom code. You will then get the value based on both the incident angle and scattering angle. We are interested in supporting this in the toolbox but we would like to gather some information about how the info is stored. That's why I ask whether you have some measurements and if you could share the format.

I dont have any measurements as of now. But the requirement is that:

rcs_at_receiver=RCS(incident_angle, scattering_angle). This RCS function shoud have varying RCS for different aspect angles. Can this be done?
