This base effect type can be included in the electronic_protect or electronic_attack technique block as one of the many available effects for a given technique. The commands listed below are the base-type commands that can be specified in the effect block for this effect type.

Note

If receiver and/or Antenna Commands are entered this will override the default use of a matched main and auxiliary channel receiver and/or antenna, respectively. In cases where these commands are used, parameters are not copied from the main channel receiver and/or antenna and all parameters of interest should be set by the user.

Commands

auxiliary_antenna_pattern <pattern-name>

Specifies the antenna pattern name to be used.

Note

This antenna pattern will become the only and default antenna pattern.

Note

This input will override (i.e., takes precedence over) the receiver antenna_pattern.

auxiliary_beam_tilt <angle-value>

Specifies the beam tilt of the auxiliary receiver. The default tilt is angle is derived from the receiver this effect is attached to if this is not defined.

Default: beam_tilt of the receiver for which the effect is attached

blanking_threshold <dbratio-value>

Specifies the blanking threshold level at which the signal will be blanked. Signal blanking will occur if the (auxiliary receiver channel)/(main channel power) >= blanking_threshold.

Default: 0.0 dB

main_jnr_thresholds <min-db-ratio> <max-db-ratio>

Specifies the main channel JNR threshold levels to use as the lower and upper levels, respectively, at which the SLB will operate with the input jamming signal.

Default: Main receivers SNR threshold as defined on the sensing receiver for the lower level and large value for the maximum upper level.

auxiliary_jnr_thresholds <min-db-ratio> <max-db-ratio>

Specifies the auxiliary channel JNR threshold levels to use as the lower and upper levels, respectively, at which the SLB will operate with the input jamming signal.

Default: Main receivers SNR threshold as defined on the sensing receiver for the lower level and large value for the maximum upper level.

saturation_effect <saturation-type> … end_saturation_effect

Input block to provide the saturation effect and it’s associated input commands.

<saturation-type>

Specifies the saturation type to be used. Available saturation effects are as follows:

no_saturation_effect

No saturation effects will be applied.

duty_cycle_limit_effect

Duty-cycle saturation effects will be applied. See saturation_duty_cycle for more information.

Default: no_saturation_effect

duty_cycle_limit <value>

Specifies the maximum duty-cycle of the incoming jamming signal at which blanking will occur. Any jamming signal with a duty-cycle greater than this value will not be blanked (i.e., the blanker will not be operational). Valid values in range of [0..1].

Default: 1.0

target_blanking_effect <target-blanking-type> … end_target_blanking_effect

Input block to provide the saturation effect and its associated input commands.

<target-blanking-type>

Specifies the target blanking type to be used. Available target blanking effects are as follows:

no_target_blanking_effect

No saturation effects will be applied.

duty_cycle_probability_effect

Probability draw and comparisons to the incoming signal duty-cycle will be used for target blanking effects.

Default: no_target_blanking_effect

probabilities … end_probabilities

Input block to provide a target blanking probability table effect and its associated input commands.

pulse_density <pulse-density> <probability-value>

duty_cycle <duty-cycle > <probability-value>

Specifies the target blanking probability for the specified received pulse-density or duty-cycle from the jamming signal. Multiple entries create a lookup table.
