Linearly frequency modulated (LFM) signals are desired in many electronic systems. For example, linearly frequency modulated continuous wave (LFMCW) radar has the good performance of lightweight, cost-effective, and high-resolution imaging. However, the presence of frequency nonlinearity in the transmitted signal will result in contrastand range-resolution degradation. In this paper, the impact of...
A novel combination of millimeterwave linearly frequency modulated (LFM) technology and new radar imaging techniques can provide a good high-resolution imaging sensor that can be inboard in unmanned vehicles, in which stringent limitations of size, weight and power consumption are required. This paper presents an approach of multiple transmission and multiple reception in elevation for vehicle-borne...
Inspired by recent advances in multiple-input and multiple-output (MIMO) radar, which has the potential to dramatically improve the performance of radar systems over single antenna systems. This paper proposes a waveform diversity-based MIMO synthetic aperture radar (SAR) concept. The fundamental difference between MIMO SAR and conventional SAR is that the latter seeks to maximize coherent processing...
Bistatic synthetic aperture radar (BiSAR) offers many operational advantages; however, it results in technical problems such as synchronization of the oscillators and adjustment of the transmit pulse versus receive gate timing. Consequently, highly accurate frequency synchronization must be ensured. Inspired by the widely used GPS for time and frequency transfer, this paper concentrates on the design...
