This base effect type can be included in the 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.

coherency_ratio <value>

Specifies the ratio of pulses that are coherently processed by the victim’s receiver. Divides the power between the coherent and noise jammer power by this ratio.

Default: 0.0

jamming_pulse_density <value>

Specifies the pulse density of the jamming signal in range [0,1] to use for this radar type.

Default: 0.1

samples_per_detection <value>

Specifies the number of pulse samples used in a single detection attempt for a target (e.g., number of Fast Fourier Transform, Integration bins used by the radar). Must be greater than 1.

Default: number_of_pulses_integrated for WSF_RADAR_SENSOR types, 1 for all other types

minimum_jammer_to_noise_threshold <db-ratio-value>

Specifies the minimum jammer-to-noise ratio that this effect is able to effect this radar type’s receiver.

Default: 0.0 dB

jammer_gain_table … end_jammer_gain_table

This block defines the jammer gain this effect exhibits as a function of the jammer-to-noise ratio and the pulse density present (i.e., achieved from the input jammer pulse density) in the victim’s receiver.

jammer_to_noise_ratio <db-ratio-value>

Specifies the jammer-to-noise ratio the following set of pulse_density_to_jamming_gain is valid for. This input can be repeated for multiple jammer-to-signal input values as required.

Default: 0.0 dB

pulse_density_to_jamming_gain <ratio> <db-ratio-value>

Specifies the jammer power gain factor on the receiver for the achieved pulse density at the victim receiver. This input can be repeated for multiple pulse_density_to_jamming_gain input values for a given jammer_to_noise_ratio as required. Pulse density input range [0.0,…1.0]. The gain lookup values are interpolated for pulse density’s that fall between two values in the table. A pulse_density of 0.0 is automatically mapped to a jammer_gain of -300.0 dB in the tables but can be overridden by the input.

Default: 0.1 0.0 dB

system_type_data <system-type-name> … end_system_type_data

Input block to provide the system type (e.g., SENSOR-TYPE, JAMMER-TYPE) specific data necessary to implement this technique for a given system type. Default data can be set up for system types not defined using the “default” string as the system type.

<system-type-name>

A string input of the system-type the following data applies to, valid values are [system-type-name | “default”]. Default data is used for unspecified system-types and if not defined no effect will be applied for the given system-type.
