因此您需要合适的测试设备与测试方法，来准确捕获雷达回波和杂散信号，进行雷达发射机及接收机指标测试，同时评估系统的抗干扰性及其他电路指标。

Suitable test system and method are need toaccurately capture and analyze the echo and clutter, even to test transmitterand receiver of Radar, and estimate the anti-jamming of Radar.

无杂散动态范围被定义为用dB表示的，接收机噪声和两个相等杂散信号的电平的差，这两个杂散信号的互调产物与接收机噪声相等。

It is defined as the difference in dB between receiver noise and the level of two equal spurious signals whose intermodulation products are equal to the receiver noise.
