Retrieval of Effective Correlation Length and Snow Water Equivalent from Radar and Passive Microwave Measurements

Remote Sensing, 2018
Current methods for retrieving SWE (snow water equivalent) from space rely on passive microwave sensors. Observations are limited by poor spatial resolution, ambiguities related to separation of snow microstructural properties from the total snow mass ...

Intelligent Detection of Low–Slow–Small Targets Based on Passive Radar

Remote Sensing
Due to its unique geometric configuration, passive radar offers enhanced surveillance capabilities for low-altitude targets. Traditional passive radar signal processing typically relies on energy accumulation and Constant False Alarm Rate (CFAR ...

Design of a Printed Dipole Antenna Array for a Passive Radar System

International Journal of Antennas and Propagation, 2013
Passive radar (or Passive Coherent Localisation) is an advancing technology for covert operation. The signal transmitted from sources of opportunity such as radio or TV stations is used as illumination for a certain area of interest.

Single receiver Long‐Term Evolution passive radar system using signal reconstruction for moving target detection

IET Radar, Sonar & Navigation
This paper presents a single‐antenna receiver passive radar system in the context of moving target detection such as trains, car, planes and UAVs, leveraging the long‐term evolution (LTE) network as an illumination source. The proposed system uses signal

A fast disturbance cancellation scheme for orthogonal frequency division multiplexing‐based passive radar exploiting reciprocal filter

IET Radar, Sonar & Navigation
This paper proposes a simple non‐adaptive approach for the suppression of direct signal and clutter contributions in a passive radar system based on orthogonal frequency division multiplexing transmissions, exploiting the properties of a reciprocal ...

Application and Performance Assessment of Adaptive Direct Path Interference Removal for Single-Channel Passive Radar Sounding

IEEE Access
We present an optimized algorithm for direct path interference (DPI) removal in single-channel passive radar systems. We demonstrate the applicability of this adaptive signal processing technique to improve signal-to-noise ratio (SNR) in passive radar ...

DETERMINING THE DISTANCE TO THE TARGET IN PASSIVE RADAR OF SURFACE OBJECTS [PDF]

Radio Physics and Radio Astronomy
Subject and Purpose. While outperforming active radar methods for range, stealth, and energy consumption, passive radar has a significant disadvantage: it cannot determine the target distance and coordinates when only one reference receiving point is ...
