Radar Advanced Environment for STK/Radar

Radar Advanced Environment for STK/Radar Radar Advanced Environment AGI has teamed with Photon Research Associates to produce the Radar Advanced Environment extension for STK/Radar. Radar Advanced Environment is an add-on module for STK that extends the capabilities of STK/Radar by introducing ground reflectivity as a contributing factor in dynamic radar assessments. It is fully integrated with STK and is compatible with UNIX and PC platforms. Radar Advanced Environment allows the user to model pulse Doppler radars and incorporates important characteristics including clutter, noise, system parameters, radar cross section and antenna type while generating reports and graphs of the radar performance. In addition, it provides a display of Radar Cross Section (RCS) maps of user determined areas on the earth.

The Radar Advanced Environment radar model provides the capability to simulate monostatic pulse Doppler radars. Users select a variety of antenna types and can define the radar performance by modifying key radar parameters such as transmit power and waveform. This model performs signal to interference and probability of detection analysis on user selected targets using an advanced physics-based frequency domain radar model. It also determines the clutter at the target's apparent range and Doppler frequency. The model considers range and Doppler ambiguity in its processing.

The Radar Advanced Environment clutter map computes and displays the ground reflectivity in a user specified area. Clutter maps are derived from a global 4.0 km resolution database and are updated dynamically during animation to reflect the changing position of the radar platform.

  • Key Features

  • Modeling of various radars

    Radar Advanced Environment allows the user to specify a wide variety of system parameters allowing the tailoring of radar system performance. Parameters include transmitted power, bandwidth and pulse compression ratio. Antenna characteristics can be completely specified including gain and sidelobes. Of special importance is the ability to identify the number of waveforms that are to be used and the frequency, pulse repetition frequency (PRF) and number of transmitted pulses for each. Frequencies from UHF to Ku, and PRFs from low through high are supported.

    Deterministic clutter

    The radar model computes clutter that interferes with target detection. The relative geometry of the radar, target and the earth are determined including grazing angle to the patches on the earth that are generating the clutter. Appropriate statistics governing the clutter behavior are applied and mapped into the target's Doppler filter.

    Radar system trade-offs

    The STK reports and graphs allow the comparison of different radar system configurations. Tradeoffs of transmitted power, antenna size and waveforms are reflected in the signal to interference ratios and probabilities of detection provided by Radar Advanced Environment. Blind speeds as a function of waveforms and target geometries can be studied.

    Deterministic clutter map

    The calculation of the RCS or clutter maps is supported by a global database with a resolution of 4km at the equator. The clutter at a given pixel in the map is a function of the radar to pixel geometry, pixel altitude and slope, a backscatter value as a function of frequency and statistical variation. Radar Advanced Environment distinguishes between water and land, and makes appropriate adjustments to the computation of the pixel RCS values.
