Mathematical model of FM autodyne radar

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
The mathematical model of operation of frequency modulated autodyne radar is developed. The model is presented in the form of an oscillator situated under influence of the proper reflected radiation from a radar object and inherent oscillator noises. Options of frequency modulation in the supply circuit and by means of capacity variation of the varicap

New ideas in FM radar

Electronics & Communication Engineering Journal, 1990
FM radars represent one of the oldest and simplest–yet at the same time one of the most versatile types of radar. The paper presents a tutorial review of the basic principles of FM radars and introduces a number of new ideas, including digital generation of wideband linear FM waveforms, and aperture synthesis with FM radar.

Ranging for stepped‐FM coded radar

Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1999
This paper focuses on radar that is used in automotive applications. It describes a stepped-FM coded radar that is free from radar mutual interference, has high resolution, and is referred to as FM-CW radar.

FM radio based bistatic radar

IEE Proceedings - Radar, Sonar and Navigation, 2005
An experimental bistatic radar system is described that detects and tracks targets to ranges in excess of 150 km from the receiver, using echoes from a non-cooperative FM radio transmitter. The system concept and limitations on performance are described, followed by details of the processing used to implement the system. An adaptive filter algorithm is

MIMO-FM: A Solution to Estimate Target Elevation with Passive FM Radar

2018 International Conference on Radar (RADAR), 2018
In this paper, we deal with the problem of estimating the target elevation in passive FM radar. Due to the large wavelength of such systems, accurate beamforming at the reception side would require unpractical large reception devices of several meter height.

Analysis and Emulation of FM Radio Signals for Passive Radar

2007 IEEE Aerospace Conference, 2007
Due to its high power levels provided, and its wide coverage, FM radio could be a good opportunity transmitter for passive coherent location (PCL) radar systems. In this paper we study the effectiveness of FM signals as radar waveforms by means of simulated and real data analysis.

Synthesis of Short-Range FM Radars with General Modulations

IEEE Transactions on Communications, 1976
A closed-form relationship is developed relating the range response, FM modulation, and demodulation functions for short-range FM radars such that, given two of the functions, the third may be determined. Synthesis and analysis techniques using the relation apply to a class of FM radars including both single- and dual-channel (directionalDoppler ...

Digital tracking filter for FM-CW radar

2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s), 2013
The paper discusses a method for improving the SNR and hence sensitivity of Frequency Modulated Continuous Wave (FM-CW) radar. In FM-CW radar, a beat signal is generated internally, with its frequency proportional to the altitude. Beat frequency measurement results in error if the input has low Signal to Noise Ratio (SNR).

Backscattering measurements by an FM radar method

IEEE Transactions on Antennas and Propagation, 1963
This paper describes a method for measuring the backscattering cross section of an arbitrary target using FM radar techniques. This method has a merit that it does not require a nonreflecting background behind the target, by the use of a high selective amplifier in the FM radar.

A Precise New System of FM Radar

Proceedings of the IRE, 1956
The paper describes a new system of fm radar by which both the range and the speed of the target can be accurately measured. The "fixed error," which is a characteristic of fm radar apparatus now in use, has been eliminated, affording correct measurement of ranges, even if they are very short.
