of Richmond, BC) launched on 14 December 2007 and remains operational. RADARSAT-2 is an Earth-imaging radar satellite which CSA and MDA (MacDonald Dettwiler Associates Ltd. Therefore, we verified that a wireless bio-radar sensor could detect heartbeat and respiration well without contact and our SNR analysis could be an effective tool to design a wireless bio-radar sensor. RADARSAT-1 was an Earth-imaging radar satellite which CSA launched on 04 November 1995 and was decomissioned on 29 March 2013. Measurement results show that the heart rate and respiration accuracy was very high. With an output power of 0 dBm and a free running oscillator without a phase locked loop circuits, a detection range of 50 cm was measured. ECG (electrocardiogram), and reference respiration signals are measured simultaneously to evaluate the performance of the sensor. The heartbeat and respiration signals acquired from the I/Q channel of the sensor are applied to the digital signal processing circuit using MATLAB. voltage-controlled oscillator, an I/Q demodulator, and analog circuits. The demonstrated sensor consists of two printed antennas, a 150 Jang et al. Based on these analysis and the measurement results, a compact, low-cost 2.4 GHz direct conversion bio-radar sensor was designed and implemented in a printed circuit board. It can detect targets with an RCS ( radar cross section) of 3 square meters flying over 200 miles away, according to web information. Especially, we measured a residual phase noise of a typical free-running oscillator and used its value for the SNR analysis. The Russian-made S-300 anti-aircraft radar used by Iran is multistatic, with components as far as 25 miles apart, and uses the S-band for its best view.

Therefore, we analyzed the SNR of the wireless bio-radar sensor, considering the signal power attenuation in a human body and all kinds of noise sources. for Radar-Frequency Bands IEEE Aerospace and Electronic Systems Society. From the outputs of FFT frequency, pulse width, pulse amplitude and time of arrival of the input signal are found out. FFT is performed on the input signal that is sampled at 105MHz by 14-bit ADC. In order to design a wireless bio-radar sensor quantitatively, the signal-to-noise ratio (SNR) in the baseband output of a sensor should be calculated. The objective of this project is to measure the radar pulse parameters like frequency, amplitude, pulse width and time of arrival of the pulse.
