Threshold Output Value: Defines the value that will be sent through to the tracker when a radar input signal exceeds the Threshold Delta value and how the input signal from that radar should be conditioned before being passed on to the next stage. The noise is averaged over this window size and the threshold delta is applied to this averaged value to check for significant power returns.
Threshold Window (m): The moving window size over which to calculate the dynamic threshold. Setting a lower threshold value provides greater detection capability but can correspondingly increase the level of false alarms. Signal levels below this threshold will be discarded. Threshold Delta (pwr): Defines the threshold above which the signal will be included for track processing. Use Static Target Detection: Select this to protect long-stationary targets from being absorbed into the clutter map.
In this scenario it is safer to dynamically suppress potential targets, but only for as long as it takes the large target to move out of range. Under normal circumstances, we would want to look for multiple targets in the same azimuth, however, when we have large targets very close to the radar, this prevents us detecting anything behind them. If a track is a certain size at a certain range, we reduce the target shadow to limit false recording by removing signals in the shadow of large targets. Use Azimuth Blanking: Select this to remove all raw radar data from the processing chain behind large returns close to the radar, to avoid unnecessary false alarms. Use Clutter Guard: This adds a margin of error to established clutter in order to avoid false alarms being created from real-time fluctuations in signal return.
Use Clutter Map: Select this for the tracker to use the saved clutter map. This is to be used in exceptional circumstances. Use FTC: Select this for the tracker to use a Fast Time Constant high-pass filter to help reduce the impact of rain on radar results. Show STC Range: Select to show the STC Range. STC helps to reduce clutter by selectively attenuating the radar signal power, within a specified range, to allow for nearby interfering factors, such as buildings, gantries, lakes etc. Use STC: Select this to enable Sensitivity Time Control to reduce clutter from nearby static objects.
