Linear‐FM random radar waveform compressed by dechirping method
IET radar, sonar & navigation, 2019This research proposes a novel linear frequency modulation (Linear-FM) random radar waveform and introduces a dechirping compression method. The proposed linear-FM random waveforms possess a thumbtack ambiguity function and low cross-correlation ...

Stepped-FM pulse radar for vehicular collision avoidance
Electronics and Communications in Japan (Part I: Communications), 1999In this paper a stepped-FM pulse radar for vehicular collision avoidance is proposed, providing anti-interference capability and high range resolution. Wide-band VCO devices have in general a linearity error over the bandwidth, which is critical issue for high-range-resolution radar. We also suggest a compensation scheme based on the LMS method for the

New developments in FM-CW radar sounding
Boundary-Layer Meteorology, 1973Simultaneous lidar and FM-CW (frequency modulated-continuous wave) radar observations are presented and both common and different features observed with the two remote sensors are described. Among the common features are Kelvin-Helmholtz (K-H) waves and turbulent structures.

Implementation of FM-Broadcasting-Based Passive Radar and Analysis of Target Detection Results
The Journal of Korean Institute of Communications and Information Sciences, 2019An FM-radio-based passive radar system is a sort of radar technique for detecting moving targets by exploiting FM-radio signal. This radar system does not require to design signal transmission parts, and thus it is classified as a passive radar.

Short Pulse, FM/CW and Chirp Radars
1976As a starting point in its discussions on the effect of atmospheric factors on short pulse, FM/CW and chirp radars the working group assigned the same fractional bandwidth and mean power to each type. This was necessary to make them equivalent and permit a valid comparison to be made.

Radio-Frequency Interference Among Linear-FM Radars
IEEE Transactions on Electromagnetic Compatibility, 1979The problem of radio-frequency interference (RFI) between radars using linear-FM pulses is examined. For a very large class of cases, the RFI is the same as if the FM were removed; for the cases not in that category, it is shown that the peak response of an unweighted receiver can be closely approximated by a hand calculation.

A New Display for FM/CW Radars
IRE Transactions on Military Electronics, 1961One of the limitations of FM/CW radars, often quoted in the literature, is in their inability to handle multiple targets. Several variations of a comparatively simple Range/Range Rate Display, capable of handling and resolving a large number of targets when used in conjunction with an FM/CW radar, are presented.
