Feasibility of Air Target Detection Using GPS as a Bistatic Radar

نویسنده

  • A. G. Dempster
چکیده

The feasibility of using GPS as a bistatic radar illuminator for the purposes of air target detection is examined. The power budget analysis is first performed assuming the use of a single satellite, but is followed by a discussion of the expected improvements when multiple satellites are employed. The analysis includes the effect of GPS signal strength dynamic range, also known as the ‘near-far’ problem. The difference between the radar cross-section (RCS) of a typical air target and ground-based clutter reflections is discussed, followed by an estimation of the effect of ground clutter on the operation of such a system.

Target Detection in Bistatic Passive Radars by Using Adaptive Processing Based on Correntropy Cost Function

In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...

Glaser Associates

This paper reviews the concept of a forward-scatter radar (FSR) which exploits the enhanced bistatic radar cross-section of a target in the forward direction (as opposed to the conventional back-scatter direction). FSR has the potential to reliably detect and track small air-vehicles with high sensitivity. Fundamentals of radar (including monostatic, bistatic, and multistatic) and a brief histo...

Bi- and Multistatic Radar

Biand multistatic radar are expected to benefit from their separation of transmitter and receiver that denies receiver recognition by ARM, favours covered operation by their silent receivers, has higher detection possibilities of stealthy objects and is less vulnerable to jamming. The requirements of synchronisation in a separated transmitter-receiver system are discussed. The processing in bis...

Test Results from a Novel Passive Bistatic GPS Radar Using a Phased Sensor Array

GPS bistatic signals have applications for remote sensing in collecting data such as soil moisture content, surface altitude or wave speed. Prior research using these signals has been limited by the low signal power of the bistatic GPS signals. Leveraging off of a previous effort that used a 15-element array, NAVSYS Corporation has developed an advanced bistatic GPS receiver that uses a 109-ele...
