For coherent jammers to wideband linear frequency modulation (LFM) radar, the ratio between jamming energy and signal energy is always constant. To enhance the jamming to signal ratio (JSR), a two-dimensional (2D) discretized coherent noise jamming (2D-DCNJ) method is first proposed in this ...
The paper presents a detection performance of the LFM radar signal using the Radon and Hough transform. Such a transforms extracts the line equation from the time-frequency image. The main problem which is considered in the paper is the autonomous search process of the LFM signal by the interce...

LFM-FSK is a new type of radar signal modulation waveform. This new waveform combines the merits of Linear Frequency Modulation (LFM) and Frequency Shift Keying (FSK). However, the range and radial velocity estimation error will be great if the system parameters design is unreasonable in ...
The UWBE design uses a wide-bandwidth (approximately 3 GHz) linear frequency modulated (LFM) waveform. Another critical requirement for GPEN radar is the need for efficient propagation of the radar waveform into the soil, which enhances... ED Adler,J Clark,P Phu,... - Radar Sensor Technolog...
